Find the measure of angle H.

Answer 1

• ABCD is a quadrilateral.
• We know, for a quadrilateral, the sum of all angles is equal to 360°.
• Here, angle A = (2x - 15)°
• Angle B = x°
• Angle C = (2x - 15)°
• Angle D = x°
• Therefore, $(2x - 15) + x + (2x - 15) + x = 360 \\ = > 2x + x + 2x + x - 15 - 15 = 360 \\ = > 6x - 30 = 360 \\ = > 6x = 360 + 30 \\ = > 6x = 390 \\ = > x = \frac{390}{6} \\ = > x = 65$
• So, the measure of angle A
• = (2x - 15)°
• = (2 × 65 - 15)°
• = (130 - 15)°
• = 115°

Answer:

115°
