x=10
Step-by-step explanation:
First square root 36 cm^2
Then you square both 8 and 6
Then you square root the sum of the two numbers.
This is called Pythagorean Theorem, which can be shown as a^2 + b^2 = c^2
Answer:
D. (3,2)
Step-by-step explanation:
Answer:
30 degrees
90 degrees
60 degrees
Step-by-step explanation:
If two of the sides are four, we know that the triangle is a right triangle so one angle is 90 degrees. if the other angle is 30, you can add them. 30+90=120. Then subtract it by 180 because all angles in a triangle add up to 180. 180-120=60.
5.28 rounded to the nearest tenth is 5.3
The height of a semisphere is equal a radius of this hemisphere.
But... if we can talk about the height of the hemisphere ;)
R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
