The formula for the area of a trapezoid is A= 1/2h (b1+b2), where h is the height and b1 and b2 are the two bases. Rewrite the formula to solve for b1 in terms of A, h and b2. b1 = ?

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

any options?

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
