Question

Given: △CDE∼△LMN

m∠C=79, m∠D=6x+11, m∠E=7x−14, and m∠N=3x+18.
The scale factor is 2
Find m∠N

Answer 1

m∠N = 42°

Explanation:

△CDE∼△LMN

<C = <L

<D = <M

<E = <N

Given:

m∠E=7x−14 and m∠N=3x+18

So

7x - 14 = 3x + 18

4x = 32

x = 8

<N = 3x+18 = 3(8) + 18 = 42

Answer 2

D.

Explanation:

Step-by-step explanation:

6x+2x=8x

-20+36=16

Put both answers for both equations into an equation

8x+16

now multiply 14 instead of having x

8(14)+16=128
