Mathematics
1 answer:
bekas [8.4K]3 years ago
3 0

Answer:

x =12

Step-by-step explanation:

The two angles are complementary, so the add to 90 degrees

5x+1/2x +24 = 90

Combine like terms

5 1/2 x +24 = 90

Subtract 24 from each side

5 1/2 x = 90-24

Change the mixed number to an improper fraction

11/2 x = 66

Multiply by the reciprocal 2/11 on each side

2/11 *11/2 x = 66*2/11

x = 6*2

x =12

topjm [15]

Answer:

B&C: tan F=0.0833 & tan H=12.0000

Step-by-step explanation:

The tangent relationship is always opposite/adjacent.

When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.

1/12 is 0.0833

When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.

12/1 is 12.
