Answer:
a. x = 82 degrees
b. All angles less than 90 degrees are 65 degrees and 33 degrees and 82 degrees in an acute triangle.
Step-by-step explanation:
A triangle has to equal to 180 degrees, add 65 and 33 together to get 98 degrees, subtract 180 from 98 to get 82 degrees. Part B is self explanatory.
It would be c I did all the calculations for it
The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.
Hope this helps :)
Just use the division property of equality: divide 60 by -16 and you will get the value of x
Answer: 42/12 or 3.5
Step-by-step explanation:
5(6)/3(-4)= -30/12
-30/12 + 6 or -30/12 + 72/12 = 42/12 or 3.5
