Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A

Answer:
1205.76
Step-by-step explanation:
The formula for volume of a cylinder is : π(or 3.14)r²h
Plug in the variables and solve
(3.14)(8)²(6)
(3.14)64(6)
384(3.14)
1205.76

Answer:
a. 100.48
Step-by-step explanation:
c = r(pi)(2)
r = 16 m
pi = 3.14
16 x 3.14 = 50.24
50.24 × 2 = 100.48
Step-by-step explanation:
1. set it equal to 0 so t=5,9
2. this is wriiten in vertex notation so vertex is (7,4)
