Answer: [tex]x=22.62^{\circ}[/tex]
Step-by-step explanation:
Given
The hypotenuse is 13 units
One of the lengths is 12 units
The marked angle is x
from the figure, we can write
[tex]\Rightarrow \cos x=\dfrac{12}{13}\\\\\Rightarrow x=\cos^{-1}[\dfrac{12}{13}]\\\\\Rightarrow x=22.62^{\circ}[/tex]
Answer:
The previous answer is wrong it's in fact 67.38
Step-by-step explanation:
You see it's sine, the 12 must be divided by 13.
Then you use the inverse sine to move it to the other side of the equation.
Where if you use a calculator will give you 67.38013505 rounded by the hundredth to 67.38 as I said.
