Answer:
The three angles of the triangle are 41°, 56° and 83°.
Step-by-step explanation:
The three angles of a triangle are given by 2x + 1, x and x + 15.
Now, we know the property of triangle, that 180° is the sum of all the angles of a triangle.
Hence, (2x + 1) + x + (x + 15) = 180°
⇒ 4x + 16 = 180
⇒ 4x = 164
⇒ x = 41°
So, 2x + 1 = 83° and x + 15 = 56°
Therefore, the three angles of the triangle are 41°, 56° and 83°.

Answer:
2
Step-by-step explanation:
The height formula given is:
h = -16t^2 + 70
That means the object will be initially (t=0) at the height 70 feet, from where it will be dropped.
If we want to know the time when the object will be at height 6 feet, we just need to use h=6 in the equation, and then calculate the value of t:
6 = -16t^2 + 70
16t^2 = 64
t^2 =4
t = 2 s
So, it will take 2 seconds for the object to be 6 feet above the valley floor.
