Question

SOMEONE HELP ASAP!!!!​

Answer 1

Answer in explanation

Explanation:

We know that 137 and (3x+41) are vertical angles eaning mthey are equilvalent.

Therefore we can write the eqaution 137= 3x+41 and solve for x.

137-41=3x

96=3x

32=x

We know that BEA and BEC are supplemntry meaning they form a 180 degree angle. And BEA is 137. we know that BEC is 180-137 which is

43

Hoped this helped,

Answer 2

x = 32

m ∠ BEC = 43°

Explanation:

(3x + 41 )° = 137° [ vertically opposite angle ]

3x + 41 = 137

3x = 137 - 41

3x = 96

x = 32

137° + m∠BEC = 180° [ Straight line angle ]

m ∠BEC = 180 - 137

m ∠ BEC = 43°
