Answer:
x° =125° y°= 125°
Step-by-step explanation:
55° + x° = 180° because they are complementry angles
solve for x by subtracting 55° from both sides
x° = 125°
x° and y° is equal because they are vertical angles
Answer:
0.79 sec
Step-by-step explanation:
Given there is a tool at the top of the building which is dropped by a worker and it follows the following equation at every instant of time .

where 
We know that this height is measured from the base of the building which means that when the tool reaches the bottom of the building it has h = 0 feet.
Let this be done at time t
h(t) = 0



t = 0.79 sec
Therefore the total time taken by the tool to reach the bottom of the building is 0.79 sec.
Because the ratio of a 45,45,90 triangle is 1:1: square root 2, x=4.

Answer:
u = 2/3
Step-by-step explanation:
Simply divide both sides by -8:
u = (-16/3)/-8
If you don't have a calc, use KCF:
u = (-16/3)(-1/8)
u = 16/24
u = 2/3
