Answer:

b=85º

a=20º

Step-by-step explanation:

Angle B is supplementary with the 45º and the 50º angle, therefore the sum of the three angles must be 180

45+b+50=180

95+b=180

b=85º

Angle A, Angle B, and the 75º angle must also add up to 180

85+75+a=180

160+a=180

a=20º

80 is 40% of what number?
andriy [413]
 80 is 40% of 200 because 40%of 100 is 40. Common sense is just to double both values, also 200 x .40 (40%as a decimal) gives you the result of 80.
