Answer:
Area = 15 m²
Step-by-step explanation:
Given:
Triangle with two side lengths, 4 m and 10 m, and an included angle, 50°.
Required:
Area of the triangle
Solution:
Formula for calculating the area of a triangle with two sides and an included angle = ½*a*b*Sin C
a = 4 m
b = 10 m
C = 50°
Plug in the values into the equation
Area = ½*4*10*Sin 50°
Area = 20*Sin 50°
Area = 15.3208889
Area = 15 m² (to 2 s.f)
