Answer:
27 cm2
Step-by-step explanation:
The answer is 27 cm 2 because if you use length x base x height you would get your answer. So 6 x 3 x 3 = 54 and then if you divide that by 2 you would get 27

Lil Pump is always right.
A semicircle is a half of a circle.
Find the circumference of a full circle then divide in half.
Circumference = pi x r x 2
Circumference = 3.14 x 9 x 2 = 56.52
Semicircle = 56.52/2 = 28.26

Answer:
Step-by-step explanation:
The two base angles are equal.
The vertex angle is 8x
The two base angles are 5x + 5x
The sum of all three angles = 180 degrees (all triangles make 180 degrees when their interior angles are added).
5x + 5x + 8x = 180
18x = 180
x = 180/18
x = 10
Therefore the vertex angle is 8*10 = 80 degrees
One of the base angles = 10* 5 = 50 degrees
The other base angle = 50 because the triangle is isosceles.
