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!
Lets look at the steps to construct
- First put compass on point A .
- Take more distance than half of AC.
- Then tick a little semicircle.
- Plot the compass on C.
- Now join the intersection point with B.
We are done
Answer:
because your just adding a zero at the end.

Answer:
1440 m³
1200 m³
Step-by-step explanation:
A local aquarium purchased a new turtle tank for their giant turtle exhibit.
If the dimensions of the tank are 15 m by 12 m by 8 m and the tank is of a cuboid shape and its volume is given by, V = (Length) × (Width) × (Height), then the volume of the tank will be
V = 15 × 12 × 8 = 1440 m³.
Again, if the dimensions of the tank are 15 m by 8 m by 10 m, then its volume will be
V = 15 × 8 × 10 = 1200 m³ (Answer)
