Answer:
Angle C = 90°
a = 15sqroot3
b = 15
Step-by-step explanation:
Solve a triangle means to find all the angles and all the sides.
Angle C must be 90° because all the angles of a triangle add up to 180°.
That makes this a 30°-60°-90° triangle so there are SHORTCUTS to finding the sides so you don't have to use trig or pythagorean thm.
SHORTCUT:
The shortest side is half the longest side. (The short leg is half the hypotenuse) and/or the longest side is twice the shortest side.
SHORTCUT:
The long leg is the shortleg•sqroot3
(advanced mode: the shortleg is the longleg/sqrt3)
So for your problem, the hypotenuse is 30, so the short leg is 15. And that makes the long leg 15sqrt3. See image.
