Answer:
∠2=92°
Step-by-step explanation:
Using an angle formula, -8x+144=2x+74
Simplification:
-8x+144=2x+74
-8x+70=2x
70=10x
x=7
Therefore, each angle is 88°
Now, because ∠2 is adjacent to one of 88°, they add up to 180°
Therefore,
180°=88°+∠2
∠2=92°
Sin32=opposite/hypotenuse, which is 12.87/23.96. (12.87/23.96)/12.87=
12.87/(23.96*12.87)=1/23.96.
For the right side to be equal, it must have 22.35 on the top (to cancel out) and 23.96 on the bottom. Since 23.96 is the hypotenuse, we have that, and since 22.35 needs to be on the top, sin67 fulfills that
Answer:
The inverse f-1(x) = (2 - x)/4 + 1.
Step-by-step explanation:
Let y = -4 /(x - 1) + 2
-4/(x - 1) = y - 2
x - 1 = (y - 2) / -4
x = -(y - 2)/4 + 1
x = (2 - y)/ 4 + 1
Now replace x by f-1(x) ( the inverse) and y by x:
f-1(x) = (2 - x)/4 + 1.
