Answer:
Step-by-step explanation:
90.9^2 - 21.2^2 = b^2
8,262.81 - 449.44 = b^2
b = 88.39326897450959189749074160142
50 degrees is one while the other two are 130 degrees
12+14+16=42 is your answe
Area = area of the square in the center + 2 * area of the 2 quarter circles.
= 5^2 + 2 * 1/4 *3.14 * 5^2
= 25 + 39.25
= 64.3 in^2 answer
lets use x as the variable in this situation
x > -2 or x is greater than negative two.
hope this helps
