Answer:
Yes, is a solution
Step-by-step explanation:
Recall that . By replacing
in the given trigonometric equation, we get 0 (zero) as a result, so this value is a solution:
The value of .
We know that,
➪ 125° + + 30° = 180°
➪ + 155° = 180°
➪ = 180° - 155°
➪ = 25°
Therefore, the value of is 25°.
Now, the three angles of the triangle are 125°, 25° and 30°.
✒ 125° + 25° + 30° = 180°
✒ 180° = 180°
