Answer:
x= 6 ± √31
Step-by-step explanation:
x^2-12x=-5
x^2 -12x +36= -5 +36
(x -6)^2= 31
√(x -6)^2= ±√31
(x-6)= ±√31
x= 6 ± √31
Answer:
59°
Step-by-step explanation:
The angles of a triangle equal 180°.
Also the angle of a straight line is 180°.
So you first find the missing bottom angle by taking 180-147 to equal 33.
Then you take 33+88+x=180
solve for x by subtracting 88 and 33 from 180 to equal 59.
