Answer:
3/5
Step-by-step explanation:
It should look like this...
x=3/5
(5*(3/5))=3
5*3 = 15
15/5=3
The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.

The coefficient of x is the slope of the line , So the slope of the above equation is -3 .

Remember from now on ,
Product of multiplying the slopes of two lines which are perpendicular to each other , is -1 .
Thus ;

m is the slope of the line which we want.

Negatives simplifies

Divide sides by 3

We have following equation to find the point-slope form of the linear functions :

x(0) and y(0) are the coordinates of the point which the line passed through.


Add sides 8

D it's store d, it's the cheapest
Divide 83.524 by pi then take half of that answer .
the answer should be 13.29 or 13.3
