Answer:
x = 9 and y = -7
Step-by-step explanation:
given:
using substitution method:
2(-4y - 19) + 2y = 4
-8y - 38 + 2y = 4
-6y = 42
y = -7
Solve for x:
x = -4(-7) - 19
x = 28 - 19
x = 9
the area of the triangle is 36
Answer:
Step-by-step explanation:
t+t+10+t+20=180
3t+30=180
3t=180-30=150
t=150/3=50
t+20=50+20=70
exterior angle=180-70=110°
