Please answer! I give brainliest when I can! It make my day :-) ASAP :-( Write a formula for the given measure. Let A represent the area in square feet, and h represent the height in feet. Identify which variable depends on which in the formula.

the area of a trapezoid with base lengths of 7 feet and 11 feet

A=

A=1/2h(7+11) or A=1/2h(77)

The area is dependent on the height and the height changes based on the length of both of the bases

Step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
