Answer:
x = 78°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
110° is an exterior angle of the triangle on the right , then
x + 32°= 110° ( subtract 32° from both sides )
x = 78°
measure of sum interior angle = (n-2)180 where n is the no. of sides
=(3-2)180
=180°
The first triangle :
110+45+y = 180
155+y = 180
y = 180-155
y = 25°
The whole triangle :
45+57+x = 180
102+x = 180
x = 180-102
x = 78°

Answer:
x = 8
Step-by-step explanation:
complementary angles sum to 90°
sum the 2 angles and equate to 90
5x + 50 = 90 ( subtract 50 from both sides )
5x = 40 ( divide both sides by 5 )
x = 8
