Area of Triangle angle (β) 139 degrees, side 90 inches and with angle (γ) 4 degrees is 307.7407424 inches².

The area of a triangle is defined as the total space that is enclosed by any particular triangle. The basic formula to find the area of a given triangle is A = a² * sin(β) * sin(γ)/(2 * sin(β + γ)), where a is side, sin(β), sin(γ) are the angles of the given triangle. Area of Triangle angle (β) 139 degrees, side 90 inches and with angle (γ) 4 degrees is 307.7407424 inches².


    Area of a Triangle Angle(β) = 139 degrees by side(a) = 90 in with angle(γ) = 4 degrees in other units

Steps:

Given that Angle (β) = 139 degrees , Side (a) = 90 in and with Angle(γ) = 4 degrees

We Know that, Area = a² * sin(β) * sin(γ)/(2 * sin(β + γ))

Substitute the values of the angle (β) = 139 degrees , the side (a) = 90 in , and the with angle (γ) = 4 degrees into the formula

90² * sin(in) * sin(139)/(2 * sin(degrees + 4))

Simplify the above equations

A = 307.7407424 in²

∴ Area of a Triangle angle (β) 139 degrees , side (b) 90 in and with angle (γ) = 4 degrees is 307.7407424 in²
