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
So 22 is 44% of something
22=44% of x
'of' means multiply
22=44% times x
percent means parts out of 100
44%=44/100
22=44/100 times x
22=44x/100
multiply boht sides by 100
2200=44x
divide both sides by 44
50=x
the number is 50
Answer:
Step-by-step explanation:
Think of <em>f</em>(<em>x</em>). Those numbers in parentheses next to the <em>f</em><em> </em>are x-coordinates, all you have to do is look in the chart and see what y-coordinate they gave you with respect to the given x-coordinates.
