The area of the triangle EFG is 7.4 square units.
Explanation:
Given that the measurements of the sides of the triangle are EF = 8, EG = 8 and 
We need to determine the area of the triangle EFG
<u>Area of the triangle:</u>
The area of the triangle EFG can be determined using the formula,

Substituting the values, we get,

Simplifying the values, we have,

Multiplying, we get,

Dividing, we get,

Hence, the area of the triangle EFG is 7.4 square units.
Answer:
33.51032
Step-by-step explanation:
Because equation is 3/4 times r to the 3 power times pi
2 to the 3 power=8
8 times 3/4=32/3
32/3 times pi = 33.51032
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
