There are lots of videos on YouTube on how to do it I’m not completely sure so I don’t want to tell you something false
Answer:
13
Step-by-step explanation:
x/y = 4
x=4y
x - y = 39
4y - y = 39
3y = 39
y= 13
65/100 = 13/20
(divide by 5 on both sides)
Hope this helped!
To find the equation take the slope 2/3
y-y(1)=m(x-x(1)
y-4=2/3(x-8) = 2/3x-16/3
Next solve for y
y=2/3x-16/3 +4(turn 4 into a fraction with a common denominator)
y=2/3x-16/3 + 12/3
y=2/3x-4/3
Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
x=34
