Answer:
11
Step-by-step explanation:
Opposite sides are congruent at parallelograms. So x+16 must be equal to 2x+5. Solve the equation;
2x+5 = x+16
x = 11 .
True
Area of a circle = πr^2
So if r = 10: area = π*10^2
= 100π
Surface area of a sphere = 4πr^2
If r = 5: surface area = 4π*5^2
= 4π*25
= 100π
I found 83.2285 I don’t know if your supposed to round it or not if so it’s 83

Answer:
(7,6)
Step-by-step explanation:
The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
