Answer:
Area of the gym floor = 100.8 square meters
Step-by-step explanation:
Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap
Area of rectangle A = 105 square meters
Area of rectangle B = 8.4 square meters
Area of the overlap =
=
= 12.6 square meters
Area of the gym floor = 105 + 8.4 - 12.6
= 100.8 square meters
Therefore, area of the gym floor is 100.8 square meters.
Answer:
1. c = 28.1, A = 19°, C = 144°
2. c = 2.0, A = 161°, C = 2°
Step-by-step explanation:
In general, if the given angle is not opposite the longest side, there will be two solutions. That is the case here.
Angle A can be found from the law of sines. It will be ...
A = arcsin(a/b·sin(b)) = arcsin(15.73/13.8·sin(17°)) ≈ arcsin(0.333261) ≈ 19.46°
or the supplement of that, 160.54°.
Angle C will be the angle required to make the sum of angles be 180°, either 143.53° or 2.47°.
Side c will be ...
c = b·sin(C)/sin(B) ≈ 47.2002×sin(C)
either 28.053 or 2.032.

There are two possible triangles:
(A, C, c) = (19°, 144°, 28.1) or (161°, 2°, 2.0)
