Question

Find the value of x. Then find the angle measures of the triangle.

Answer 1

Answer:

x=35°

3x= 105°

Step-by-step explanation:

$40 + 3x + x = 180$

$40 + 4x = 180$

$4x = 180 - 40$

$4x = 140$

$x = \frac{140}{4}$

$x = 35$

$3x = 3(35) \\ 105$

Answer 2

3x + 40 + x = 180
-40. -40
——————————-
4x. 140
—. ——-
4. 4

x = 35
