Question

State the theorem and find the value of x

Answer 1

the sum of the interior angles of a triangle is always 180°

x = 12

Explanation:

• the sum of the interior angles of a triangle is always 180°

2x + 11 + 70 + 75 = 180

2x = 180 - 11 - 70 - 75

2x = 24

x = 12

----------

check

75 + 70 + 11 + 2 * 12 = ( remember pemdas)

75 + 70 + 11 + 24 =

180°

the answer is good
