Answers:
M for 1 is: 114
M for 2 is: 34
Why?
First you need to find out what the angle is for the corner to the left of angle 1 to do so
180-135 which equals 45
then to find on you take 180 (the sun of all interior angles in a triangle equal 180) and subtract all the angles give...
180-21-45= 114 (which makes since because angle one is obtuse and so is it)
Now for angle to you need to find the corner that is next to angle 1 to do so you do...
180-114 (because angle equals 114) this equals 66
Then you do 180-66-80 to get angle 2 which equals 34
Hope this helps :D
Answer:
16.9
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 46)° = 180° - 136° = 44°
----------------------------------------------------------------
tan46° = 
= 
Multiply both sides by 23
23 × tan46° = b, thus
b ≈ 23.8 ( to the nearest tenth )
-----------------------------------------------------------------
cos46° = 
= 
Multiply both sides by c
c × cos46° = 23 ( divide both sides by cos46° )
c = 
≈ 33.1 ( to the nearest tenth )
$34 divided by 4 = $8.5 per hour.
$8.5 Times 10 hours = $85
So she would earn $85
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
