Step-by-step explanation:
Volume of the pyramid =
area of its base Multiply by its height
The base of the pyramid is a right angled triangle its legs are 14 and 18
Area triangle = 
(the length of its base)(the length of its height)
In the right angled triangle its base is one of the two legs of the right angle and its height is the other leg
So area of the base = 
The volume = 
Answer:
1/10
Step-by-step explanation:
1/5 to land on the spinner, and 1/2 to land on tails. Compound prob = we gotta multiply the probabilities so we get 1/10

Step-by-step explanation:
Measure of the angle’s complement is 47.42 degree and measure of the angle’s supplement is 137.42 degree
<em><u>Solution:</u></em>
Given that architect designs a porch support that forms a 42.58 angle with the roof.
To find: measure of the angle’s complement and measure of its supplement
<em><u>Finding measure of the angle’s complement:</u></em>
Two angles are Complementary when they add up to 90 degrees
To determine the complement, subtract the given angle from 90
measure of the angle’s complement = 90 - 42.58 = 47.42
<em><u>Finding measure of the angle’s supplement:</u></em>
Two angles are supplementary when they add up to 180 degrees
To determine the supplement, subtract the given angle from 180
measure of the angle’s supplement = 180 - 42.58 = 137.42
