Answer:
1. measure of angle E is 90 degrees
2. Measure of angle F + measure of angle G is 90 degrees
Step-by-step explanation:
Angle E is 90 degrees because it is marked as a right angle (the square)
A triangle has 180 degrees so if E is 90 degrees then the other 2 also have to equal 90 degrees
If the perimeter is 200 ft and the area is 2100 square feet...
P = 2l + 2w
A = l * w
The dimensions would be 30 ft by 70 ft.
This triangle would be acute none of the angles are greater than or equal to 90.
