What is the area of the following trapezoid in square feet? A-B:
135 ft2
165 ft2
82.5 ft2
64.9 ft2

82.5 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = h (b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 7.5, b₁ = 7 and b₂ = 15 , then

A = × 7.5 × (7 + 15) = 0.5 × 7.5 × 22 = 82.5 ft²

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
