What is the measure of 1?
95°
90°
80°
85°
Answers
Answer:
85°
Step-by-step explanation:
We need to use the angle fact that angles in a quadrilateral add up to 360° and that a right angle is 90°, using this information we can for an equation to find the value of 1. Lets call "1" x so we don't confuse it with an angle. So,
x + 85 + 100 + 90 = 360
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 90 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
x + 85 + 100 + 90 = 360
→ Simplify equation
x + 275 = 360
→ Minus 275 from both sides to isolate x
x = 85
The measure of angle '1' is 85°
Answer:
85°
Step-by-step explanation:
∠1+85°+100°+90°= 360°
∠1 = 360°- 275°= 85°
∠1 =85°

Help asap please ! Please explain too
Answers
Answer:
D) 35
Step-by-step explanation:
angles that are opposite are equal, so the 45 degree angles is in th triangle too. angles on a straight lines are equal to 180, so 180 - 80 = 100.
So far we have two of the angles, 100+45=145
Angles in a triangle are equal to 180, so 180-145 =35
vertically opposite angles are the same, so the ? is 35 degrees

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Conor buys 75 tokens for games at the arcade.\
And, The price to play each game is 3 tokens.
Here, Conor has already played x games.
Hence, The value of expression is equivalent to the number of tokens that remain is,
⇒ 75 - 3x
⇒ 3 (25 - x)
Thus, The value of expression is equivalent to the number of tokens that remain is,
⇒ 3(25 - x)

how would you differentiate this problem using the quotient rule?
Answers
1/3 d/dx [ (2x^2-x^5)/3x^1/2].
Then factor x^2 out of 2x^2-x^5.
Then by using the negative exponent rule you should have
1/3 d/dx [ x^2(2-x^3)x^-1/2 ]
Then multiply x^2 by x ^-1/2 by adding the exponents.
1/3 d/dx [ x^3/2 (2-x^3)]
Then differentiate.
You should get x^1/2 - (3x^7/2)/2.

What is a quadratic equation?The equation of the form ax² + bx +c is known as a quadratic equation.
The given equation is 2.1/x + 1 (4/5) =(3/10)x.
Simplify the equation as follows:
2.1/x + 1 (4/5) =(3/10)x
2.1/x + 9/5 = (3/10)x
2.1 + (9/5)x = (3/10)x²
21 + 18x = 3x²
3x² - 18x -21 =0
3x² - 21x + 3x -21 =0
3x(x - 7) + 3(x - 7) =0
(x - 7)(3x + 3) =0
x - 7 =0 or 3x + 3 =0
x = 7 or x = -1
