Answer:
first angle: 27 degrees
second angle: 135 degrees
third angle: 18 degrees
Step-by-step explanation:
Represent each angle with a variable x and sum them to 180 degrees, the total angle measure of a triangle. So...
first angle: x
second angle: 5x
third angle: 2x/3
x+5x+2x/3=180 Combine like terms
6x+2x/3=180 Change the 6x terms to have a denominator of 3
18x/3+2x/3=180 Combine like terms
20x/3=180 Cross multiply to solve for x
20x=540 so x=27
Now plug in to get angles:
first angle: 27
second angle: 135
third angle: 18
Check: 27+135+18=180
Here ur asked to divide 16 by 5/8:
16/1 ÷ 5/8
find the reciprocal of the divisor (5/8) which means to flip, and then multiply it by 16/1:
16/1 X 8/5 = 128/5, now change it into a mixed number.
25 3/5
To find the approximately volume you will use the formula for finding the volume of a cylinder:
V = pi x r^2 x h
3.14 x 0.5^2 x 21
V = 16.485
The volume is approximately 16.49 cubic inches.
Here ya go. I hope this helps! :) (It was much easier to do this than to try and type it out, in my opinion)
