Answer:
∠ QPR = 56°
Step-by-step explanation:
Δ RST is isosceles ( 2 congruent sides ) , then base angles are congruent
∠ SRT = =
= 68°
∠ PRQ and ∠ SRT are vertically opposite angles and are congruent , so
∠ PRQ = 68°
Δ PRQ is isosceles ( 2 congruent sides ), then base angles are congruent , so
∠ QPR = =
= 56°
The value of tan a is 2.9098
Explanation:
The given value is
Now, we shall find the value of sin (a), using the identity,
Substituting the value of cos (a), we get,
Subtracting both sides by 0.1056, we have,
Taking square root on both sides, we get,
Now, we shall substitute the value of sin (a) and cos (a) to determine the value of tan (a) in the identity
Thus, the value of tan (a) is 2.9098
