One angle has +3x^2 degrees measure
another has +8x^7 degrees measure
total has 180 degrees measure
so the third angle has a measure of 180 -(3x^2 +8x^7) degrees
hope this will help you
(Y-Y1)/(X-X1)

20/-8
-2 1/2
The slope is -2 1/2
Answer:
20
Step-by-step explanation:
a negative times a negative is a positive
Answer: first picture is for y=-5/3x + 3
Step-by-step explanation:
According to the picture, you can assume that angle X is congruent to angle Y due to their triangle shape. Here is the work:
1. Set the equations equal to one another: 4x-8 = 2x
2. Move the variables to get the "x" values on one side: 2x = 8
3. Divide by 2 to get "x": x = 4
4. Plug in "x" into the Angle X equation: 4(4)-8 = angle x....16-8....8
Angle X is 8 degrees. Hope this helped :)
