Using his telescope tommy watches a bald eagle as it sits ono top of a cliff. The telescope is positioned so that the line of sight to the eagle forms a 38 degree angle of elevation. The telescope sets s1.3 m above the ground and the base of the telescope is 116 m from the base of the cliff. Round to the nearest tenth
Answers
Question :
How high above the ground is the eagle?
Answer:
91.9 m
Step-by-step explanation:
From the diagram :
We can obtain h, using the trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = h
Adjacent = 116
Tan 38° = h / 116
0.7812856 = h / 116
h = 0.7812856 * 116
h = 90.629132
Eagle's height above the ground :
h + 1.3m
h = 90.629132m
Height above the ground = 90.629132 + 1.3 = 91.9 m above the ground.

Pqr=qps work out the value of qps
Answers
Answer:
89°
Step-by-step explanation:
Total inner degree of PQRS = (4-2)*180° = 360°
PST is a straight line : 180°
angle PSR = 180-128
=52°
angle RQP + angle QPS = 360 - 52 - 130 = 178°
Angle PQR = Angle QPS
Angle QPS = 178/2 = 89°

Answers
Answer:
46 degrees
Step-by-step explanation:
You should know that measures QRS, which form a horizontal line, measures up to 180 degrees. (Just like a right angle adds to 90 degrees). So, TRS is 42 degrees and URT is 92 degrees, that would make QRU measure 46 degrees because 180 - 92 - 42 = 46 degrees.
Hope that helps you!! Please give me brainliest!! ;)
Answer:
42°
Step-by-step explanation:
A horizontal, or flat line is 180°. This means the total measures of ∠TRS, ∠URT, and ∠QRU, are 180°. We can subtract the given measures from 180 to find the measure of ∠QRU.
∠TRS = 42°
∠URT = 92°
Subtract 42 and 92 from 180.
180 - 42 - 92 = 46
∠QRU = 42°
m∠QRU in circle R is 42°.

find x to the nearest tenth
Answers
The value of the base length x of the right angle triangle to the nearest tenth is 18.4.
What is the value of x?From the diagram;
Angle θ = 49°Hypotenuse = 28Base length x = ?We use trigonometric ratio since its right angle triangle.
Cos = Adjacent / Hypotenuse
Cosθ = Base length / Hypotenuse
Cos( 49° ) = x / 28
x = Cos( 49° ) × 28
x = 0.656059 × 28
x = 18.4
Therefore, the value of the base length x of the right angle triangle to the nearest tenth is 18.4.

A softball pitcher throws a softball to a catcher behind home plate. The softball is 3 feet above the ground when it leaves the pitcher's hand at a velocity of 50 feet per second. If the softbal's acceleration is - 16
Ft/s2. This can be modeled with the equation (h=height, t=time) h(t)=16t^2 +50t+ 3
What is the time at which the softball would hit the ground it it were not hit or caught?
A.) .5 seconds
B.)3.12 seconds
c.) 3.18 seconds
D. ) 2.42
Answers
Answer:
Using their equation and the fact that the ball will fall 3 ft before reaching the ground:
3 = 16 t^2 + 50 t + 3 represents the given situation
16 t^2 + 50 t = t (16 t + 50) = 0
16 t + 50 = 0
t = 50 / 16 = 3.12 sec

(a + b)^8
The above expression is a binomial expression, and the nth term of the expression is:
(a + b)^n = nCr * a^(n - k) * (b)^k
