Answer:
B.76 square feet
Step-by-step explanation:
SA=B+L
70 degree angle for T,R,Q and T,R,S is 140 degree
The value of sin(30°) is 1/2.
<h3>What is Trigonometry?</h3>
The branch of mathematics concerned with specific functions of angles and their application to calculations.
The diagram is attached below:
We know,
sin 30= Perpendicular/ Hypotenuse.
As, the hypotenuse is the opposite side of the right angle and the perpendicular is opposite to the given angle.
So,
sin 30 = 5/10
sin 30 = 1/2
