Answer:
Step-by-step explanation:
multiply by 6
4-24x+21=-54x+5
54x-24x=5-4-21
30x=-20
x=-20/30=-2/3
Answer:
7,802,000,000
Step-by-step explanation:
subtract: 1,020,000,000 - 239,800,000
The rule for angles in a triangle is that they all need to add up to 180°, so you can make the three expressions equal 180 and solve:
x + 10 + x + 2 + 9x - 8 = 180
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16
So your answer is 16

Answer: -4/3</h3>
============================================================
Explanation:
cos(A) = 0.6 = 6/10 = 3/5
Recall that csc is the reciprocal of sine.
If csc(A) = -1.25, then sin(A) = 1/csc(A) = 1/(-1.25) = -0.8 = -8/10 = -4/5
Then we would have
tan(A) = sin(A)/cos(A)
tan(A) = sin(A) ÷ cos(A)
tan(A) = (-4/5) ÷ (3/5)
tan(A) = (-4/5) * (5/3)
tan(A) = -4/3
