Isosceles triangle because there are 2 angles that's the same.
Answer:
D, 10.
Step-by-step explanation:
10+8=18 4/3x18=24
The only way to do that is with +7 and -7 .
Let angle = x
sinx = 43.2/72.5
=> x = 36.57 degrees
Answer: 147 cm²
Step-by-step explanation:
Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.
A = πr²
A = (3)(7)²
A = 147 cm²
