2s+4=5(-4-2s)
Distribute the 5
2s+4=-20-10s
add ten s to both sides
12s+4=-20
subtract 4 from both sides
12s=-24
divide by 12 on both sides
s=-2
Hope this helps :D
We have to calculate AC ( hypotenuse ):
AC² = 29² + 28²
AC² = 841 + 1444
AC² = 2285
AC = √2285
AC = 47.8
And for the angle C:
cos C = Adjacent / Hypotenuse
cos C = 38 / 47.8
cos C = 0.794979
∠ C = cos ^(-1) 0.794979
∠ C = 37.35° ≈ 37°
Answer: ∠ C = 37°.

Answer:
86
Step-by-step explanation:
Let the number be 10x + y. So, the reversed number is 10y + x.
The sum is 154.
So, (10x + y) + (10y + x) = 154
⇒ 11x + 11y = 154
⇒ x + y = 14 ..... (1)
Again, given that ones digit in the original number is 2 less than the tens digit.
So, y = x - 2 ...... (2)
Now, solving (1) and (2) we get,
x + x -2 = 14
⇒ 2x = 16
⇒ x = 8
So, from equation (2), y = x - 2 = 8 - 2 = 6
Therefore, the original number is 10x + y = 10 × 8 + 6 = 86 (Answer)
Answer:
D. Angle P, Angle OPQ, Angle QPO
Step-by-step explanation:
The angle is at P so P must be either between the two other letters or be by itself so D is the correct answer.
