Answer:
m∠B = 119°
Step-by-step explanation:
- the measure of c and 112 are on the straight angle and they are both equal 180°
c = 180 - 112 = 68
∠c = 68°
- the sum of the interior angles of a triangle is 180°
- the measure of third angle = the sum of the interior angles - the sum of two angles
a = 180 - (51 + 68) = 61
∠a = 61°
- the measure of 61 and b are on the straight angle and they are both equal 180°
b = 180 - 61 = 119
∠b = 119°
also you can go on other way
- an exterior angle of a triangle is equal to the sum of the opposite interior angles
51 + 68 = 119
Answer:
$188
Step-by-step explanation:
250 (original price) - 62 (loss) = 188
