Hello.
1. Understand that this requires inverse trigonometry.
2. For A, we can use sin^-1 if we want (we could use cos^-1 or tan^-1 as well because all sides are given)
Definition of sin^-1 with how it is derived
sin(theta) = O/H <—> sin^-1(O/H)
Angle A: (When calculating an angle, ensure that your calculation is in degree mode instead of radian mode.) 2ND, then QUIT on TI
sin^-1(7/25) = 16.26020471°
(round as needed)
Angle &: (also in degree mode)
All angles of a triangle add to 180°.
1. 180° - (angle B + Angle A) = Angle &
2. 180° - (90° + 16.26020471°) = 73.73979529°
(round as needed)
To quickly check: 16° + 90° + 73° = 180°, as expected for a triangle
From the picture you provided,
The angle values make sense because that triangle represents a 30-60-90 degree triangle. (Also, a good trick is to know that the smallest angle of a triangle will always have the smallest side value, and the largest angle has the largest side value.)
Unless we have an equilateral triangle!
Good luck to you!
Answer: V=7.605π
Step-by-step explanation:
The cylinder formula is V=πr^2h
Substitute the values.
V=π(1.3)^2(4.5)
V=π(1.69)(4.5)
V=7.605π
Hope this helps!
The 17500 job will pay tax of (17500-5700-3650)=8150*0.10=815
The 18000 job will pay tax of 8350*0.10+300*0.15=880
The difference in pay is therefore 500-(880-815)=$435

(4,7) is just 4 and 7 but [4,7] is all the points between 4 and 7. I am pretty sure this is correct, but i could be wrong. Hope this helped!
