Answer:
62.4 ft²
Step-by-step explanation:
The unmarked horizontal dimension at the bottom of the triangle is ...
(8 ft)sin(30°) = 4 ft
The unmarked vertical dimension of the triangle (the height of the trapezoid) is ...
(8 ft)cos(30°) ≈ 6.93 ft
Then the area of the trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)((4 ft+7 ft) +(7 ft))(6.93 ft) ≈ 62.4 ft²

The mnemonic SOH CAH TOA can remind you of the relationships between right triangle dimensions and angles.
Sin = Opposite/Hypotenuse ⇒ Hypotenuse×Sin = Opposite
Cos = Adjacent/Hypotenuse ⇒ Hypotenuse×Cos = Adjacent
Answer:What is the question?
Step-by-step explanation:
42/x = 30/100
Flip to get x on top and multiply 42 by 100. You get 4200 and then div that by 30 to get 140.

Answer:
<BCE=130°
Step-by-step explanation:
<BCE + <HCE=180° (Angles on a straight line)
<BCE+50°=180°
<BCE=180°-50°
<BCE=130°
