Answer:
x=81
Step-by-step explanation:
all triangles = 180 degrees
180 - 18 = 162
162/2 = 81
81 is your answer
The value of r is -24
Step-by-step explanation:
Given points are:
(1,r) and (5,-4)
Let the points be:
(x1,y1) = (1,r)
(x2,y2) = (5,-4)
m = 5
The slope is given by:

Hence,
The value of r is -24

Answer:
64.94
Explanation
You arrange the numbers in such a way, to be in line with their decimal points like this:
70.7
-5.76
Then you subtract. Notice that on top of the 6 is nothing which is equal to 0
So then what is the problem u need help with? I'd be happy to help.
So get b alone.
A=bh
Divide by h
A/h=b
b is alone
And just to rearrange:
b=A/h
