Question

Hey can someone solve this 4 me​

Answer 1

Answer:

∠a = 50°

∠b = 130°

∠c = 130°

Explanation:

Following Vertical Angles Theorem:

• ∠(2a - 50)  =  ∠a

• 2a - 50 = a

• 2a - a = 50

• a = 50

A straight line has 180° angle measure, ∠c and ∠a lies on a straight line

• ∠c + ∠a = 180°

• ∠c + 50° = 180°

• ∠c = 180° - 50°

• ∠c = 130°

Also, following vertical angle theorem:

• ∠b = ∠c

• ∠b = 130°
