False, because a^2+b^2=c^2 and no matter what numbers substitute for which ever variable the answer isn’t going to be true
54 makes sense because it is less than a 90 degree angle and 80 wouldn't go through.
<span>5[8 - (9x - 7)] + 6x = 0
5[8 -9x + 7] + 6x = 0
5(15 -9x) + 6x = 0
75 - 45x + 6x = 0
-39x = -75
39x = 75
x = </span>

A) 14.66
Arc length is equal to radius multiplied by the central angle in radians not degrees
Answer:
Shown Below
Step-by-step explanation:
Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.
180 - 67 = 113.
Inside angles of a triangle all add up to 180. Using that we can create the equation:
(x + 27) + x + 113 = 180
simplify.
2x + 140 = 180
subtract 140 on both sides.
2x = 40
divide both sides by 2
x = 20
substitute x into the asked equation.
(20 + 27) = 47
47 is your answer.
