The measure of angle C is 20.5 angles C and D are complementary angles Find m
Kobotan [32]

Answer:

69.5 if C and D both add up to 90, M=90 if both angles C and D were complementary to combine to a supplementary.

Step-by-step explanation:

You're trying to find m which is a variable for measurement for the "D" angle.

Info Given:

20.5 for angle C

Unknown for angle D

Both angles are Complementary.

_____________________________________________

I have 2 answers for this (The question was stated unclearly so I have 2 interpretations of this)

1st Answer:

If you're asking to solve for M but the C and D angles add up to 90 then do

90 - 20.5 = 69.5

2nd Answer:

We know that both angles are complementary which are 90-degree angles.

If we combine them then the angles add up to 180.

So C and D add up to form a Supplementary Angle.

20.5+69.5 + m = 180

Then M could possibly be 90.

Seven ninths minus one third

An easy way to do questions like these is by converting the fractions into decimals, at least I used to find it easier by doing so when I first encountered them. 
So,
7/9 as a decimal is 0.77
1/3 as a decimal is 0.33

You can do;

0.77 - 0.33

You are left with;

0.44

Which in it's simplest fraction form is;

11/25.

Your answer is 11/25.

I hope this helped, if you need help with understanding how to conver then do let me know! ;3

The area of a triangle is 30 square feet. If<br> the base is 4 feet, then what is the height?
ExtremeBDS [4]
Height=15

Explanation:
Area of a triangle= 1/2base x height
Plug in information
30=1/2 x 4 x h
Solve 1/2 x 4 = 2
30= 2 x h
Divide both side by two
30/2=2 x h/2
Solve:
15= h
