The angle above the y is 90 degrees ( shown by the little square)
The 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48
Y = 42
Answer:
.645 x 10^1
Step-by-step explanation:
Answer:
x = -8
Step-by-step explanation:
Solve for x by getting rid of the fraction.
414/(x-10) = -23
414 = -23(x-10)
414 = -23x + 230
184 = -23x
-8 = x
<span>68=-16t2+64t+8
16t2-64t+60=0
4t2-16t+15=0
(2t-5)(2t-3)=0
t=5/2 or 3/2
The object is at 68 feet after 3/2 secs, and returns to 68 feet after another second..</span>
