Answer:
c:) 150 in²
Step-by-step explanation:
It's basically and SAS triangle
SAS is Side, Angle, Side
side 15 in angle 90° and 20 in
a = 20 in
b = 25 in
c = 15 in
Angles:
A = 53.1301 °
B = 90 °
C = 36.8699 °
Other:
P = 60 in
s = 30 in
K = 150 in2
r = 5 in
R = 12.5 in
Agenda:
A = angle A
B = angle B
C = angle C
a = side a
b = side b
c = side c
P = perimeter
s = semi-perimeter
K = area
r = radius of inscribed circle
R = radius of circumscribed circle
