Answer:
A = 58
B = 112
Step-by-step explanation:
A + B = 180 Supplementary angles
B = 2A - 24 Given
Substitute for B in the first equation
A + 2A - 24 = 180
3A - 24 = 180 Add 24 to both sides
3A = 180 + 24 Combine the right
3A = 204 Divide both sides by 3
A = 204/3
A = 68
B = 2A - 24
B = 2*68 - 24
B = 136 - 24
B = 112
Answer:
sin(x) = 
x = 16.26°
Step-by-step explanation:
First use Pythagorean theorem to find the length of the hypotenuse. Use
. Since we know a and b we can plug in to find c. When we plug in we get:
. When we solve this out we get 25 = c.
Now that we know the value of c, we also know sin(x) =
. Using this we see that sin(x) =
.
To get the exact degree value of x, take the inverse sin of
:
which gives us 16.26020° rounded to 16.26°
48 “divided by” (-8) = (-6)
(-40) “divided by” 8 = (-5)
12 “minus” (-2) = 14
18 “plus” (-12) = 6
18 “plus” (-20) = -2
22 “times” (-0.5) = -11
