Answer:
The height of tree house is 70.71 feet
Step-by-step explanation:
We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground
Refer the attached figure
Length of rope AC = Hypotenuse =100 feet
The top of a tree house to the ground forms a 45∘ angle of elevation from the ground =
We are supposed to find the height of tree house i.e.AB = Perpendicular
So, Using trigonometric ratio
Hence The height of tree house is 70.71 feet
Answer:
a =9
b= 28
Step-by-step explanation:
The parts of the ratio must be equal
5:7:a = 20:b:36
How do we get from 5 to 20
We multiply by 4
So multiply the first by 4
5*4:7*4:a*4 = 20:b:36
Ratio 1
5*4 =20 true
Ratio 2
7*4 =b
28 = b
Ratio 3
4a = 36
Divide by 4
4a/4 = 36/4
a = 9
-6 + 5x = 6x - 7 Subtract 5x from both sides
-6 = x - 7 Add 7 to both sides
1 = x Switch the sides to make it easier to read
x = 1
Answer:
- The angles do not share a special relationship.
Step-by-step explanation:
Angles 13 — 20 are right angles. Angle 12 is complementary to given angle 7, so is 90°-72° = 18°. Angle 10 is vertical with angle 12, so is also 18°.
There is no special relationship between right angle 14 and acute angle 10.
