Answer:
70.7 deg, 19.3 deg
Step-by-step explanation:
The sum of the measures of complementary angles is 90 deg.
One angle measures x.
The other angles measures 51.4 deg less than x, or x - 51.4.
The sum of their measures equals 90.
x + x - 51.4 = 90
2x - 51.4 = 90
2x = 141.4
x = 70.7
x - 51.4 = 70.7 - 51.4 = 19.3
Answer: 70.7 deg, 19.3 deg
Answer:
Area of 9 cm circle = PI*radius^2 = 254.47
Area of 9 cm sircle = PI*4*4 = 50.27
Are of shaded region = 254.47 -50.27 = 204 sq cm
Answer is the bottom one on the list.
Step-by-step explanation:
Answer: 22 square feet
Step-by-step explanation:
Using Heon's formula, the are can be found with:
Where s is half the perimeter
a, b and c are sides
Perimeter = a + b +c
24 = 9 + 10 + c
c = 24 - 9 - 10
c = 5 feet
s = 24 / 2 = 12
Area
= 22 ft²
