These two angles are vertical angles. Vertical angles are congruent, so you have to make an equation.
2x + 29 = 9x - 13
7x = 42
x = 6 degrees
Answer:
178cm
Step-by-step explanation:
x=180
y=160
0.4(x+y)+42 =
0.4(180 + 160) +42 =
0.4(340)+42=
136+42=
178cm
Answer:
Then study bro but here is your ans
Step-by-step explanation:
7 c
8 a
A+b+c=180
subsittute
x+25+x-5+c=180
2x+20+c=180
minus 20 both sides
2x+c=160
mius 2x
c=160-2x
