- Use the Law of SInes to find the measure of angle C:
(sinC)/c = (sinA)/a
sincC = c(sinA<span>)/a
C = sin</span>⁻¹(c·sinA / a)
Plugging in numbers:
C = sin⁻¹(83·sin(31) / 44<span>)
= </span>sin⁻<span>¹(0.97155)
= 76.3°
- We know that the sum of the internal angles of a triangle is 180°, therefore:
B = 180 - (A + C)
= 180 - (31 + 76.3)
= 180 - 107.3
= 72.7°
- Therefore the corret answer is C: angle B is 72.7°</span>
You can see that the two angles (38° and 7) form a line or 180°. So, angle 7 and 38° must add to 180°. So, angle 7 is:
Your answer is
142°.
