Answer:
The area of the triangle is 61.2 sq. cm.
Step-by-step explanation:
Given : A triangle has sides of lengths 10 cm and 16 cm and the measure of the angle between them is 130 degrees.
To find : The area of the triangle?
Solution :
The area of triangle when two sides and one angle between them is given is
[tex]A=\frac{1}{2}\times a\times b\times \sin\theta[/tex]
Where, a and b are the sides of the triangle
a=10 cm and b=16 cm
[tex]\theta=130^\circ[/tex] is the angle between two sides
Substituting the values in the formula,
[tex]A=\frac{1}{2}\times 10\times 16\times \sin 130[/tex]
[tex]A=80\times 0.766[/tex]
[tex]A=61.28cm^2[/tex]
Therefore, The area of the triangle is 61.2 sq. cm.
