Answer:
c is 110 degrees
b is 70 degrees
a is 20 degrees
Step-by-step explanation:
for c, 180-70=110
for b, 180- angle c=180-110=70
for a, 180-90-angle b=180-90-70=20
Answer:
80,94º
Step-by-step explanation:
What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).
So I calculated the tangent of the angle of the tourist.
The formula is tan=Oposite side/adjacent


And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).
I hope it helped.
