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!
Well, its 10 for 4. so 8 is 20, 12 is 30, 16 is 40 20 is 50, and 24 is 1 hour, 2 tabels is half the time so 5 min... so it would take -1 hour and 5 min
The equations are:
1. 2.35y = 4.70
2. k/3 = 17
3. 4 = 10w
4. 55x = 111
5. 8 = a/5
Answer:
the equations that apply are:
1. 2.35y = 4.70
3. 4 = 10w
4. 55x = 111
Step-by-step explanation:
We want to determine which if the equation we can use the division property of equality to solve.
1. 2.35y = 4.70
We can divide both sides by 2.35, so that
2.35y/2.35 = 4.70/2.35
y = 4.70/2.35
THIS WORKS
2. k/3 = 17
THIA DOESN'T WORK
3. 4 = 10w
dividing both sides by 10
4/10 = 10w/10
w = 4/10
THIS WORKS
4. 55x = 111
Divide both sides by 55
55x/55 = 111/55
x = 111/55
THIS WORKS
5. 8 = a/5
THIS DOESNT WORK

Hopefully this is correct
