Question

i dont understand how to do this​

Answer 1

Answer:

Step-by-step explanation:

2.

AE=2BD

4x+14=2(4x+5)

4x+14=8x+10

8x-4x=14-10

4x=4

x=1

5.2

AB+ED=2FC

AB+36=2×20

AB=40-36=4

next.

m∠J+m∠N=180

6x+5+9x+20=180

15x=155

3x=31

x=\frac{31}{3}

∠N=9x+20=31×3+20=93+20=113

∠M+∠N=180

∠M+113=180

∠M=180-113=67°
