Sorry if it is wrong
Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
32.68346376° = B
32.7° = B
Answer:
X + (X+1) +(X+2)
(X+(X+1)) = 3 *(X+2) + 17
2X +1 = 3X + 6 +17
X = -22
So the three integers are -22 -21 and -20
Double-Check *******************
(-22 -21) = 3 * (-20)
-43 = -60 +17

Answer:
-11x +2
Step-by-step explanation:
−(9x + 8) − 2(x − 5)=
-9x -8 -2x +10 =
-11x +2
