Answer:
(B) The measure of angle SUT is equal to 90 degrees
Step-by-step explanation:
It is given that in In triangle STU, 
.
We can see from the triangle and also the given condition that the triangle will be right triangle as it is satisfying the Pythagoras theorem.
that is:
where u is the hypotenuse, s is the base and t is the perpendicular.
Thus, the angle SUT should be of 90°.
Thus, The measure of angle SUT is equal to 90 degrees.
Hence, option B is correct.
Here you go. I hope you understand. Ask if you don't.
We want sin A. sin A is defined here as opp / hyp, and the values here are
sin A = 9.5 / 11 = 0.864, which, when rounded off to the
nearest hundredth, is 0.86 (answer)
Answer:
20.6
Step-by-step explanation:
Use the trig function Cosine to find the length of the ramp. The cosine function is defined as the ratio adjacent side over hypotenuse. The base 20 is the adjacent side to the angle 14 while the length of the ramp is the hypotenuse. Using the function we write, cos 14 = 20 / x. Solve for x.
Cos 14 = 20 / x
x*Cos 14 = 20
x = 20 / cos 14
x = 20.6
Unit rate for $40 for 100 books is $0.40 and the unit rate for $75 for 250 books is $0.30. so the $75 for 250 books is better. to find unit rate you do 40/100 and 75/250
