In this question, it is given that An inverse trigonometric function is used to find the value of an unknown obtuse angle in a triangle. The inverse function returns the angle 68°.
Since the angle is obtuse angle, it means the measurement of the angle is greater then 90 degree. And to find the angle measurement, we have to subtract the given angle from 180 degree.
So the unknown angle is
And that's the required answer .
Answer:
= 11y + 1z
Step-by-step explanation:
So to rewrite it so that we can find the side, we just need to isolate the a variable.
So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be 
It would be 120.
Look at the first column, 40. It’s basically multiplication and you can just use a calculator.
For example, 40 x 1 = 40,
And if you looks the second column, it’s being multiplied by 2. Which would be 40 x 2, you just have to multiply 3 x 40 which is 120.
Sorry for my english
For 12 minutes because 23 x 12 is 2.76 and 25 minus 22.24 is 2.76
