Answer:
See below
Step-by-step explanation:
A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.
Answer:
The triangle C
Step-by-step explanation:
As we know:
The Law of Sines (or Sine Rule) is very useful for solving triangles:
where:
- a, b and c are sides.
- A, B and C are angles
Let analyse 3 answers:
a. Wrong, because we do not know the measure of each angle
b. Wrong, we do not the the lenght of side that is opposite the the angle 40°
c. True, we know the measure of the other missing angle is:
= 180° - 70°- 30°
= 80°
and we know one side is: 10m
Hence, using the Sine Law, we can find out the side of the other 2 sides of the triangles.
C is a linear-equation I think
Answer:
