Given:△ABC∼△DEF, ∠C is a right angle, AB=17, AC=15, BC=8, m∠B=62∘, DE=34, EF=16,and DF=30.What is the measure of ∠D?

Answers

Answer 1

Answer:

Answer:

28°

Step-by-step explanation:

We can see the scale factor is 2 from the side lengths:

8→16, 15→30, 17→34

Corresponding sides are:

AB and DE
AC and DF
BC and EF

Corresponding angles are opposite to corresponding sides:

∠C≅∠F
∠A≅∠D
∠B≅∠E

m∠A = 90° - 62° = 28°

Therefore

m∠D = 28°

How many seconds did it take for the object to hit the ground?
How many seconds did it take for the object to reach 1000 feet

Answers

Answer:

time = 0 seconds

Time to hit ground = 7.906 seconds

time = 0 seconds

Step-by-step explanation:

t = 0

-16(0)^2 +1000 = 1000

Time for ball to reach ground:

-16t^2 +1000 = 0

-16t^2 = -1000

t^2 = -1000/-16

t = squareRoot (-1000/-16) = 7.906 seconds
