Answer:
A = 2700 ft^2
Step-by-step explanation:
The area is given by
A = l*w
Convert yds to ft
1 yd = 3 ft
90 yds = 90 *3 = 270
A = 10 * 270
A = 2700 ft^2
<h3>
Answer: B. 40</h3>
For any triangle, the three angles always add to 180
(y+10)+(2y)+(50) = 180
3y+60 = 180 ... combine like terms
3y+60-60 = 180-60 ... subtract 60 from both sides
3y = 120
3y/3 = 120/3 .... divide both sides by 3
y = 40
