This is an acute scalene triangle
The triangle is acute since all three angles (58, 57, 65) are less than 90 degrees
The triangle is scalene as the angles are all different. So this leads to the sides being different lengths. No two sides are the same length.
Answer:
27π cm²
Step-by-step explanation:
step 1
Find the area of the complete circle
The area of the circle is equal to
A=πr²
we have
r=9 cm
substitute
A=π(9)²=81π cm²
step 2
Remember that the area of complete circle subtends a central angle of 360°
so
using proportion
Find the area of a sector formed by a central angle that measures 120°
81π/360°=x/120°
x=120°*81π/360°
x=27π cm²
