(21, 28)
Step-by-step explanation:
Multiply coordinates by 7.
Answer:

Step-by-step explanation:
So we have:

First, distribute:

Combine like terms:

Add:

So, in the a+bi format, we will have:

Answer:
x = 16.6666666667
Step-by-step explanation:
24x4 - 18x3 + 4x2 - 3x =0
24x4 = 96
18 x 3 = 54
4x2 = 8
96-54+8= 50
50/3 = 16.6666666667
B= 60
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18
hope this helped :)
