Question

answer attempt 1 out of 2 180 - 37 - 63 x y ( ) 7 8 9 ÷ 4 5 6 × 1 2 3 - 0 π + enter func s ans

Explanation:

Step1: Recall triangle - angle - sum property

The sum of interior angles of a triangle is 180°.

Step2: Set up the equation

We have \(110^{\circ}+40^{\circ}+(8x - 18)^{\circ}=180^{\circ}\).
First, simplify the left - hand side: \(110 + 40+(8x-18)=180\), which is \(150 + 8x-18 = 180\), then \(132+8x = 180\).

Step3: Solve for x

Subtract 132 from both sides of the equation: \(8x=180 - 132\), so \(8x = 48\).
Divide both sides by 8: \(x=\frac{48}{8}=6\).

Answer:

\(x = 6\)
