Question

question 4 5.6 class practict solve for x. 22 solve for y.

Explanation:

Solve for \( x \):

Step 1: Identify the triangle type

The triangle is equilateral (all sides and angles equal), so each angle is \( 60^\circ \). Thus, \( 3x - 6 = 60 \).

Step 2: Solve for \( x \)

Add 6 to both sides: \( 3x = 60 + 6 = 66 \).
Divide by 3: \( x = \frac{66}{3} = 22 \).

Solve for \( y \):

Step 1: Use equilateral side length

In an equilateral triangle, all sides are equal. So \( y + 7 = 12 \).

Step 2: Solve for \( y \)

Subtract 7 from both sides: \( y = 12 - 7 = 5 \).

Answer:

For \( x \): \( 22 \)
For \( y \): \( 5 \)
