Answer: 4) x° = 33.5°
5) x° = 31°
Step-by-step explanation: 4) It is supplementary i.e. the angle add up to 180° .
(4x+5)° +41° = 180°
4x+46 = 180°
4x = 180-46 = 134
4x = 134/4 = 33.5°
5) It is complementary i.e. angles add up to 90°
x°+(2x-3)° = 90°
3x - 3 = 90
3x = 93
x = 31°

6 (5)^2-5(4)+8
30^2-20+8
900-20=8
880-8=872
ANSWER:872
(3j, 3k) and (3/j, 3k)
So if their x values have the same signs and their y values have the same signs, they are in the same quadrant.
If j is negative, both 3j and 3/j would be negative. If j is positive then both 3j and 3/j are positive.
And 3k is the same as 3k.
