Question

ABCD is a Rhombus angle a=50 find b

Answer 1

Answer:

Value of b = 130°

Step-by-step explanation:

In a rhombus,

Sum of adjacent angles = 180°

So,

ㄥa + ㄥb = 180°

50° + ㄥb = 180°

ㄥb = 180° - 50°

ㄥb = 130°

Answer 2

Answer:

A /-------------/B

/ /

D /________/C

A = 50°

B = 50°÷2 = 50°+25°=75°

180°-75°=105°
