Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
Distance equals velocity times time.
d=vt
v=d/t
v=(3*2/5)km/5min
v=(6/5)/5
v=6/25 km/min
v=0.24 km/min
Answer:
4 and 3/4 inches less for April
and 1 and 1/2 inches less for March
Step-by-step explanation:
Answer:
V = 1000 in³
Step-by-step explanation:
The volume of a cube of side length s is V = s³.
If the side length is 10 in, then the volume, V, is (10 in)³, or V = 1000 in³
