180(x - 1)
A quadrilateral has 4 sides, so 180(3) = 540
80 + 110 + 75 = 265
540 - 265 = 275
Last measurement is 275
hope this helps

Answer:-23
Step-by-step explanation:
Its -23
We have been given that in ΔSTU, the measure of ∠U=90°, ST = 9.7 feet, and US = 4 feet. We are asked to find the measure of ∠T to the nearest degree.
First of all, we will draw a right triangle using our given information.
We can see that US is opposite to angle T and ST is hypotenuse of right triangle.
We know that sine relates opposite side of right triangle to hypotenuse.



Now we will use arcsin to solve for measure of angle T as:


Upon rounding to nearest degree, we will get:

Therefore, the measure of angle T is approximately 24 degrees.
