Answer:
x = 79
Step-by-step explanation:
All triangles have a sum of 180°. Knowing this, we can solve for the unknown angle.
56 + 23 + ? = 180
79 + ? = 180
? = 101
The variable x is known as an exterior angle. That and the angle we just solved for are supplementary meaning they add up to 180°.
101 + x = 180
x = 79
Answer:72
Step-by-step explanation:Given : A cone has a diameter of 18 units and height of 8 units.
We have to determine the volume of the given cone.
We know Volume of cone = 1/3


Where r is radius of cone
h is the height of cone
Given : diameter = 18units so, radius is half of diameter = 9 units
height = 8 units
Substitute, we have,
Volume of cone = 1/3

Simplify, we have,
Volume of cone = 
Thus, the volume of given cone is 72π cubic units.
Answer:
Supposing that every squre is 1cm^2 large
- The rectangle A has an area of 32cm^2
- The rectangle B has an area of 20cm^2
Total area: 52cm^2
