Answer:
79°
Step-by-step explanation:
A triangle has 180° in it so 180 - 82 =98- 19=79
The first one is -30 seconds
the second one is 20 meters
the third one is 0
volume of a cylinder is area of the base times the height
diameter 8 means radius r=4
V = πr²h = π(4²)(10) = 160π
Answer: 160π cubic meters
It's not clear if you need an approximation; I'll leave the calculator stuff to you.
Answer:
x = 35 degrees.
Step-by-step explanation:
(x\°) + (20+x) \°=90\°
want to solve for solve for x
2x = 90 - 20
2x = 70
x = 70 / 2
x = 35 degree
9 cm. since the smaller quadrilateral is half the size of the larger one, all the measurements will be half the size as well.
