Q. The area of a triangle is 381 . Two of the side lengths are 10 and 93 and the included angle is acute. Find the measure of the included angle, to the nearest tenth of a degree.Answer:
Area Formula Explanation: The area of a triangle can be calculated using the formula:Area = (1/2)×a×b×sin(C)where a and b are the lengths of two sides, and C is the included angle between those sides. We are given that the area is 381, and the side lengths are 10 and 93. Let's denote the included angle as θ.
Rearranging Formula: We can rearrange the formula to solve for sin(θ):sin(θ)=a×b2×AreaPlugging in the given values, we get:sin(θ)=10×932×381
Calculate sin(θ): Now, let's calculate the value:sin(θ)=930762sin(θ)=0.8193548387
Find Angle θ: To find the angle θ, we need to take the inverse sine (arcsin) of the value we calculated:θ=arcsin(0.8193548387)
Calculate Angle θ: Using a calculator to find the value of θ to the nearest tenth of a degree, we get:θ≈55.1∘
