8.80 if it's the 40°/.
2.20 if it's the 10°/. processing fee
13.20 for how much he paid
-3,2 means on quadrant 4 and 1,2 is in quadrant 1
The base is 16 and height of each triangle is 2
I think it would be 4.
8 breaks down to 4(2) and 12 breaks down to 4(3). Let me know if that helps!
ANSWER
C) Triangle
EXPLANATION
Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.
We use the sine rule and cosine rule to find the missing sides and angles.
If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.
