Question

11. Using the triangle below, set up and solve
an equation in order to find the value of x.

Answer 1

x = 27.4

Explanation:

`\sf \angle Q+ \angle R+ \angle S=180^(o)`

`\sf 34.6 + 118 + x = 180`

Add 34.6 and 118 = 152.6

`\sf 152.6+x=180`

Subtract 152.6 from both sides.

`\sf x=180 - 152.6`

Subtract 152.6 from 180 = 27.4.

Therefore, the missing angle "x" is 27.4.
