Find the measure of each side indicated. Round to the nearest tenth.
Answer:
Step-by-step explanation:
to find x we can use tangent function
tan 31= x/9
0.60=x/9
x=0.60*9=5.4 choice B
The measure of x side.
We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.
We have to determine the value of x.
Therefore we use here the trigonometric ratio
What is the tan ratio?[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]
Therefore we get
tan 31= x/9
tan(31)=0.60
0.60=x/9
Isolate the x
x=0.60*9
x=5.4
Therefore option B is correct.

write an equation that is perpendicular to x - 3y =3 and passes through the point (5,-9) in slope-intercept form.
9514 1404 393
Answer:
y = -3x +6
Step-by-step explanation:
The perpendicular line will have the coefficients of x and y swapped (and one of them negated), and will have a constant appropriate to the point the line needs to go through.
The equation will look like ...
x -3y = 3 . . . . . . . . . . . . . given line
3x +y = constant . . . . . . perpendicular line
where "constant" can be found by substituting for x and y.
3x +y = 3(5) +(-9)
3x +y = 6 . . . . equation in standard form
To put this in slope-intercept form subtract 3x:
y = -3x +6

2 math question please help me 30 point
Answer:
1. B: 12 BB 18 FB,, 2.
Step-by-step explanation:
1. make the equation (198 + 33x) + 24x = 882 because there are a certain number of each ball (x) and 6 more footballs. since each football is 33 dollars, you do 33 x 6 which is 198, and then keep 33x and 24x. It is all equal to 882 since that is the final price. First, you subtract 198 on each side and combine the like terms (33x + 24x). Now it is 684= 57x and you divide 684 by 57, which equals 12. That means that there are 12 basketballs and 12 + 6 footballs, which is 18.

Step-by-step explanation:
Step 1: Define Equation
8x - 3 = 2(x - 1/2)
Step 2: Solve for x
Distributive 2: 8x - 3 = 2x - 1Subtract 2x on both sides: 6x - 3 = -1Add 3 to both sides: 6x = 2Divide 6 on both sides: x = 1/3Rewrite the sum of 75+18 as a product of a number and another sum
Answer:
(2)(9) + 75 = 75+18
Step-by-step explanation:
(2)(9) + 75 = 75+18
The expression written as a product of a number and another sum is 3(25 + 8)
Given the expression 75 + 18, we are to write as a product of a number and another sum.
First we need to find the GCF of 75 and 18
75 = 3 * 25
18 = 3 * 6
Since 3 is common to both D+GCF, we can factor it out from the expression to have:
75 + 18 = 3(25 + 8)
Hence the expression written as a product of a number and another sum is 3(25 + 8)
