Answer:
59˚
Step-by-step explanation:
The sum of all the angles in a triangle is always 180 so:
38 + 83 + x = 180
121 + x = 180
x = 59
-10 because its a negative and that's the opposite of the greatest itreger
If you plug in 90 into theta, the expression becomes sin(180), which has a value of zero. Therefore 90 cannot be a solution to this equation. Hope this helps.
Each book costed about $18.77
To do this problem do this:
9b = 187 - 18
This is because since you have 18 dollars left over subtract it from the total amount of money you had before.
9b = 169
Divide:
b = $18.77
To check you work multiply in 18.77, 9 times and add 18 dollars to it:
18.77(9) = 169
169 + 18 = 187
