I do not understand what to do , more explicitly sorry :(
90 degrees converted to radians is pi/2 or π/2 radians.
Answer:
Your answer is A.
Hope this helps!
Step-by-step explanation:
Line r's equation is
y = - 4/3x - 4
And Line s's equation is
y = 2/5x - 2
(8x2.3)= (18.4)
(2.1x4)= (8.4)
Now you should have:
41-9+18.4-15+8.4
9+18= 27
15+8.4= 23.4
Should have:
41-27-23.4= -9.4
10 + 15x + x + 10
= 16x + 20
