If the cylinder is closed at both ends the formula is
πdh + 2π(d/2)^2 where h = height and d = diameter
Answer:
48 and 132 degrees
Step-by-step explanation:
supplement=s
one angle=2s+36
2s+36+s=180
3s+36=180
3s=144
s=48
2(48)+36=132
Therefore, 48 and 132 degrees
I hope this helped and have a good rest of your day!
A triangle 45 – 45 – 90 degree (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of 1:1:√2
if hypo = 3√2 then side = 3
answer
a = b = 3
-------------------
<span>30-60-90 Triangle
</span>long leg = short leg times √3
hypo = twice the short leg
given long leg = 5√3
so
short leg = b = 5
hypo = c = 2(5) = 10
