Question

o triangulo rst e isoceles sendo rs igual rt calcule o valor de x

Answer 1

a) 70 + 70 + x = 180
140 + x = 180
x = 180 - 140
x = 40°

b) 2x + 2x + x = 180
5x = 180
x = 180 / 5
x = 36°

c) y+ 40 + 40 = 180
y + 80 = 180
y = 180 - 80
y= 100°

x + 80 + 90 = 180
x + 170 = 180
x = 180 - 170
x = 10°

Answer 2

Resposta:

Explicação passo-a-passo:

A) 110 + t = 180

t = 70

2t + x = 180

2x (70) + x = 180

140 + x = 180

x = 180 - 140

x = 40°

B) x + 2x + 2x = 180

5x = 180

x = 36°

C) 90 + 40 + 40 + x = 180

170 + x = 180

x = 180 - 170

x = 10
