Answer:
angle 4 is 31
angle 5 is 59.
Explanation:
M<4 and M<5 add up to a right angle which is 90 degrees . so you put it in a equation form.
2x-5+4x-13=90
rearrange it
2x+4x-5-13=90
6x-18=90
add 18 on both sides
6x=108
divide 6 from both sides
and you get x= 18
Plug in x for angle 4 =2(18)-5 = 31
plug in x for angle 5 = 4(18)-13 = 59
