Question

1. find the values of x and y. (18y + 5)° (10x - 61)° (x + 10)°

Explanation:

Step1: Use vertical angles property

Vertical angles are equal. So, \(10x - 61=x + 10\)

$$

Step2: Use linear - pair property

\((18y + 5)+(x + 10)=180\) (since they form a linear pair). Substitute \(x = 7\) into the equation:

$$
LATEXBLOCK1
$$

Answer:

\(x = 7,y = 9\)
