Answer:

Answer → 63°

Step-by-step explanation:

» m<3 and m<4 are supplementary angles.

☑ Supplementary angles are angles that measure up to 180°

${ \tt{m \angle 3 + m \angle 4 = 180 \degree}} \\ { \tt{117 \degree + m \angle 4 = 180 \degree}} \\ { \tt{m \angle 4 = 180 \degree - 117 \degree}} \\ { \tt{m \angle 4 = 63 \degree}}$

What should be the first step to solve the equation?

allochka39001 [22]

Answer:

Step-by-step explanation:

You will need to get rid of the parenthesis to make the problem easier for you to work with. Since there is a number in front of the parenthesis, you will need to distribute that to both numbers in the parenthesis.

For this example, you would multiply the 9 to both the x and -1, and then 8 to both 2x and 2.

D is between C and E, CD = x 2 , CE = 32-2x, and DE = 12x. Find CD, DE, and CE.

Gemiola [76]

Answer:

CD = 4
DE = 24
CE = 28

Step-by-step explanation:

The segment addition theorem tells you ...

CD +DE = CE

x^2 +12x = 32 -2x

Subtract the right side to put this in standard form.

x^2 +14x -32 = 0

(x +16)(x -2) = 0

x = -16 or 2

In order for DE to have a positive length, we must have x > 0. So ...

CD = x^2 = 2^2 = 4

DE = 12x = 12(2) = 24

CE = 32 -2x = 32 -2(2) = 28

Assuming order doesn't matter, we can use the probability formula nCr. Using a calculator, you get that there are 210 possible combinations. However, if order did matter, then you would use nPr, in which case would the answer be 5040.
