Answer:
26.8°
Step-by-step explanation:
4x - 20 + 6x - 7 = 90
10x -27 =90
10x = 90+27
10x= 117
x = 11.7
so, the angle R = 4x-20 =4(11.7)-20
= 46.8-20 = 26.8°
-30 is the answer for your question
Answer:
(0, - 2)
Step-by-step explanation:
The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.





When x = 0, y = - 2.
