Answer:
Angle 6 = 46°
Angle 7 = 134°
Angle 8 = 77°
Step-by-step explanation:
Angle 6 = 180 - 134 (Due to the angles on a straight line add up to 180 property)
Angle 6 = 46°
Angle 7 = 180 - 46
Angle 7 = 134°
360 = 56+148+(2 x Angle 8)
2 x Angle 8 = 360-204
2 x Angle 8 = 156
Angle 8 = 78°

Answer:
answer is {-4.42, 12.54}
Step-by-step explanation:
v^2 - 8v - 59 = -2
v^2 - 8v = 57
(v - 4)^2 - 16 = 57
(v - 4)^2 = 73
Taking square roots:-
v - 4 = +/- √73
v = √73 + 4 or - √73 + 4
v = -4.54 , 12.54
Simplest for answer = 4 5/8
If you use the pothaorian theorym (A squared + B squared= C squared) youll be able to figure out the right answer is 65.
