Answer:
The answer would be C.
Step-by-step explanationIt is C.!!!!!
Given: cos A = 5/13 = adj side / hypotenuse
The the opp side is given by (hypo)^2 = (adj)^2 + (opp)^2. Here,
13^2 = 5^2 + (opp)^2, so that
(opp)^2 = 169 - 25 - 144. Then opp = +12. All of these lengths are in Q I.
opp 12
Then sin A = -------- = -------- (answer)
hyp 13
Answer:
b
Step-by-step explanation:
it looks like the right anwser
a triangle adds to 180 degrees
we have 90 and 40 so the hypotenuse is 50 degrees
The answer is 7.03 × 10<span>-2</span>
