Answer:
A
Step-by-step explanation:
We are given that:
And we want to find:
Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:
Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.
Our answer is A.
The value of .
We know that,
➪ 95° + (3 +4)° + (4
- 3)° = 180°
➪ 3 + 4
+ 95° + 4° -3° = 180°
➪ 7 + 96° = 180°
➪ 7 = 180° - 96°
➪ 7 = 84°
➪ =
➪ = 12°
Therefore, the value of is 12°.
Now, the three angles of the triangle are 95°, 40° and 45° respectively.
✒ 95° + 40° + 45° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.
