Answer:
x = 60
y = 30
Step-by-step explanation:
Adjacent angles are supplementary.
(5x -180) +x = 180
6x = 360 . . . . . . . . . . add 180, collect terms
x = 60 . . . . . . . . divide by 6
Opposite angles are congruent.
2y = 60 . . . . . . 2y = x
y = 30 . . . . . . . .divide by 2
The value of x is 60; the value of y is 30.
Answer:
29 in ^3
Step-by-step explanation:
6 sides
2 of which are smaller than the other 4.
12 x 1/2 x 4 = 4 longer sides
5 x 1/4 x 4 = 2 shorter sides
12 x 1/2 = 6
6 x 4 = 24
5 x 1/4 = 1.25
1.25 x 4 = 5
5 + 24 = 29
29 in ^3
add the two equations together
5a+5b=25
-5a+5b=35
------------------
0 + 10b =60
divide by 10
b=6
5a + 5b = 25
5a +5(6) = 25
5a +30 =25
subtract 30 from each side
5a =-5
divide by 5
a = -1
Answer (-1,6)
or a=-1 b=6
You are expected to memorize the general shape of the sine function, including where the peaks and zero crossings are. The graph shows you the value of
