Since you already know two are 90 and 40 add them together and you get 130.
A triangle has 180 degrees so minus 130 from that
180-130=50

Christopher is hanging Christmas lights along the perimeter of his house by using his 15 foot ladder. The base of the ladder is placed 4 feet away from the base of his house. How far up the house does his ladder reach?
Answers
Answer:
14.45 feet
Step-by-step explanation:
The set up is a right angled triangle;
The length of the ladder = hypotenuse = 15foot
The base of the ladder is the adjacent = 4feet
The height of th house is the opposite = x
Using the pythagoras theorem;
hyp² = opp² + adj²
15² = opp²+4²
opp² = 15²- 4²
opp² = 225 - 16
opp² = 209
opp = 14.45feet
Hence the ladder reaches 14.45 feet up the house

Step-by-step explanation:
There are several ways to solve this problem, but I think the easiest way is just to find the mean.
There are 12 total data points, and adding them all up you get 266.
mean = 266/12 = 22.167
The line in the middle of the box plot represents the mean, so the answer must be B.

66
Which equation best describes these data?
Answers
Answer: C. n = 4r + 50
Step-by-step explanation:
The equation is in the form: y =mx + c
y is the number of flowers used.
x is the row number.
Solving for m. Pick any two points. (1, 54) and (2, 58)
m = (Y₂ - Y₁) / (X₂ - X₁)
= (58 - 54) / (2 - 1)
= 4
Solving for c. Use a point to fill up the formula and find c; (1, 54)
y = mx + c
54 = 4 * 1 + c
c = 54 - 4
c = 50
Formula will therefore be;
y = 4x + 50
or;
n = 4r + 50
Solve each equation.

The probability of spinning an even number and flipping heads is..
Answers
Answer: 20% Chance
Step-by-step explanation:
Probability of flipping heads on a coin is 50% and this wheel landing on a even number is 40% you multiply .50 and .40 and you get .20.
Probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).
What is probability?
" Probability is a mathematical expression which represents ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability= (Number of favourable outcomes) / (Total number of outcomes)
For Independent Event
P(A∩B) = P(A)×P(B)
According to the question,
'A' represents the probability of spinning an even number
'B' represents the probability of flipping heads
Possible outcomes on spinner = { 1, 2, 3, 4, 5}
Favourable outcomes of spinning an even number = 2
Total number of outcomes = 5
Substitute the value in the formula we get,
P(A) = ( 2 / 5)
Possible outcomes of flipping a coin = { head , tail}
Total outcomes of flipping a coin =2
Favourable outcomes flipping heads = 1
P(B) = (1 / 2)
Probability of spinning an even number and flipping heads P(A∩B)
A and B are independent events
Substitute the value of P(A) and P(B) in the formula we get,
P(A∩B) = ( 2/ 5)×(1/2)
= 2 /10
Hence, probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).

A steel ball is traveling through water with a speed of x meters per second, where x is positive. The drag force, F, in newtons, N, is: F = 0.5 + 0.004(x + 50)(x-2.5). At what speed in meters per second does the ball have a force of 0.5 N, on it?
Answers
Answer:
x = 2.5m/s.
Step-by-step explanation:
Given that F = 0.5 + 0.004(x + 50)(x – 2.5), where x is the speed in m/s and F is the force in N. To know the speed, x, with F = 0.5N, we have:
0.5 = 0.5 + 0.004(x + 50)(x – 2.5)
This gives
0.004(x + 50)(x – 2.5) = 0 (after adding –0.5 to both sides).
For the multiplication to be 0, (x + 50)(x – 2.5) = 0 because 0.004 is not equal to 0.
Hence
x = –50 or x = 2.5
Since it is said from the question that x is positive then x = 2.5m/s.

The two stadiums with the largest capacities are Marshfield Stadium and Bowden Stadium. Marshfield Stadium has a capacity of 7,675 more than Bowden. If the combined capacity for the two stadiums is 210,355, find the capacity for each stadium.
Answers
Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
Step-by-step explanation:
Let x = Capacity of Marshfield Stadium.
y = Capacity of Bowden.
As per given, we have
x - y = 7,675 (i)
x+y = 210,355 (ii)
2x = 218030 (iii)
[tex]\Rightarrow\ x= \dfrac{218030}{2}\\\\\Rightarrow\ x= 109015[/tex]
Put value of x in (i) , we get
109015 - y = 7675
⇒ y= 109015 - 7675
⇒ y= 101,340
Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
