I think 678 to the nearest hundred is 700.
Answer:
6n + 24
Step-by-step explanation:
Answer:
8.8 = X
Step-by-step explanation:
-12.6x - 4.9x = -154
-17.5x = -154
Divide both sides by -17.5. Since there's already a -17.5 with the X, they cancel each other out.
X = -154 / -17.5
X = 8.8
As with any triangle, the sum of angles is 180°.
(a)
(x -5) +(3x +30) +35 = 180 . . . . . sum of angles is 180
4x +60 = 180 . . . . . . . . . . . . . . . . collect terms
4x = 120 . . . . . . . . . . . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . . . . . . . . . . . . divide by 4
(b)
Angle A = x -5 = 30 -5 = 25
Angle B = 3x +30 = 3*30 +30 = 120

Answer: B) 49.22</h3>
========================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(43) = 36/x
x*cos(43) = 36
x = 36/cos(43)
x = 49.2237885995494
x = 49.22
