Yes you are right because will be 102 - 52 = 50 degrees
Answer:
Step-by-step explanation:
(1). A = π r²
A = 4 π
Area of shaded region is = or
(2). C = 4 π
In this case, the length of the bigger arc and the area of shaded region happen to be the same.
The length of the arc ADB is or
If vertex angle is 42, and the base angles are congruent, this is an isosceles triangle, they each measure: 180-42/2. They each measure 69 degrees. The length of sides don't matter.
The answer is 78 feet of fencing. This is because you need to find the perimeter of the yard. To find the perimeter of the yard, you add the sides together, so 21+21+18+18 = 78.
Answer:
Use L x W x H
Step-by-step explanation:
So...
5 x 12 x 8 = 480
