Answer:
B. x = 15, m∠Q = 75°
Step-by-step explanation:
Given:
m∠P = 105°
m∠Q =
Angles P and Q are supplementary angles
To find value of and m∠Q.
Solution:
[Sum of supplementary angles =180°]
[Substitution ∵ m∠P = 105° and m∠Q =
]
Subtracting both sides by 105°.
Dividing both sides by 5.
∴
∴
Answer:
B = 54°; a ≈ 1.86; b ≈ 4.19
Step-by-step explanation:
The remaining angle is ...
B = 180° -105° -21° = 54°
The law of sines tells you the side lengths are in proportion to the sines of the angles:
a = 5·sin(A)/sin(C) ≈ 1.86
b = 5·sin(B)/sin(C) ≈ 4.19
