Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth.
Answers
Answer:
Step-by-step explanation:
use an ASA triangle with law of sine
since we know that 180 = 20 +45 + C .. solve for C = 115°
now use law of sines c/ sin(C) = b/sin(B) .. and solve for b
Sin(20)*100/sin(115) = b
b = 37.73774 ft
that's the hypotenuse of the 45 triangle
SOH CAH TOA to remember how trig functions fit
use b*Cos(45) = adj
26.6846 = adj
The bird is 26.7 ft. from the ground

Answer:
a = 16
w = 125
x = 120
y = 55
Step-by-step explanation:
FINDING 'a'
31 = a + 46 / 2
62 = a + 46
16 = a
FINDING 'w'
* This section looks Non-Isosceles trapezoid so I will be following the rule according it
w + 55 = 180
w = 125
FINDING 'y'
y = 55
- Because of corresponding angles
FINDING 'x'
* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.
x + 60 = 180
x = 120

Answers
Answer:
-1.4
Step-by-step explanation:
There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2
This means that every increment is worth 0.2.
If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.

For integers a, b and k, we know that a >12, b > 20 and a < b. If b=7k, what is the value of k ?
Answers
This question is incomplete, the complete question is;
For integers a, b and k, we know that a > 12, b < 20 and a < b. If b=7k, what is the value of k ?
Answer: the value of k = 2
Step-by-step explanation:
Given that;
a > 12
b < 20
a < b
If b = 7k
Now if k = 1 {b = 7k = 7}
b would be equal to 7 but b has to be greater than 20
IT CANT BE
if k = 2 { b = 7k = 14}
b would be equal to 14, a is greater than 12, b has to be less than b; 14 < 20,
a has to be less than than b ( 12 < 14 )
IT IS
if k = 3 {b = 7k = 21}
b would be equal to 21, so b is greater than 20 and a is less than 21
IT CANT BE
Therefore the value of k = 2

A drawing has a scale of 1 mm: 20 cm. What
is the scale factor of the drawing?
Answers
The scale factor of the drawing is 200.
Scale Factor of a DrawingThe first step to take when looking for the scale factor of a drawing is to ensure both measurements are on the same unit.
Given a scale for a drawing to be: 1 mm: 20 cm
1 cm = 10 m
Therefore:
20 cm = 200 mm
Scale factor = 200/1 = 200.
Therefore, the scale factor of the drawing is 200.
