HELP PLEASE!

Answer 1

Answer:

x = 25

Step-by-step explanation:

This is an equilateral triangle as all 3 angles are marked as equal.

Hence the 3 sides are equal

Equate any 2 and solve for x

4x - 30 = 3x - 5 ( subtract 3x from both sides )

x - 30 = - 5 ( add 30 to both sides )

x = 25

As a check on the sides

4x - 30 = (4 × 25) - 30 = 100 - 30 = 70

3x - 5 = (3 × 25 ) - 5 = 75 - 5 = 70

2x + 20 = (2 × 25 ) + 20 = 50 + 20 = 70

confirming that x = 25
