Question

Find value of x, 50 points

Answer 1

35

Explanation:

All angles add up to 360 degrees

Answer 2

x = 60°

Explanation:

Forming the equation,

→ (2x - 10°) + (2x + 40°) + 90° = 360°

Now the value of x will be,

→ (2x - 10°) + (2x + 40°) + 90° = 360°

→ 4x + 120° = 360°

→ 4x = 360° - 120°

→ x = 240°/4

→ [ x = 60° ]

Hence, the value of x is 60°.
