What is the value of x?

62 is the answer to your question

one quick way to know the answer is to know that the two opposite interior angles has to add up to the outer external angle, so x + 38 = 100

B. 62°

Step-by-step explanation:

First, solve the unknown interior angle. Interior angles and exterior angles add up to 180°.

? + 100 = 180

? = 80

The sum of the angles of a triangle is 180°. Form and solve the following equation.

x + 80 + 38 = 180

x + 118 = 180

x = 62

70

step-by-step explanation:

2*5=10

4*15=60

60+10=
