Answer:
Area of ΔQRS = 2.3 square inches
Step-by-step explanation:
From the given information,
<S + <Q + <R =
51 + 44 + <R =
95 + <R =
<R = - 95
=
<R =
Applying the Sine rule, we have;
=
=
Using =
=
r =
= 2.9483
r = 2.9 inches
Also, =
=
q =
= 2.0559
q = 2.0 inches
From Herons formula,
Area of a triangle =
s =
= 3.6
Area of ΔQRS =
= 2.2895
Area of ΔQRS = 2.3 square inches
