Question

Two congurent, isocoles triangles are joined as shown to form a parallelogram. the largest angle of the parallelogram is 116 degrees

write two equations
solve them to find the value of A and the value of B

Answer 1

64°, 52°

Explanation:

• 2a+b=180°
• a+b=116° ⇒ b=116°-a
• 2a+116°-a=180° ⇒ a=180°-116°= 64°
• b=116°-64°= 52°
