I NEED HELP! What is the area of the Triangle?
2 answers:
Area of a triangle is usually found by the formula
the height is tricky because it is not given. there are some formulas for finding height and stuff, but the easiest way to calculate area without height and a given value for each side is by using the formula
So the base is 7 units, hypotenuse 25, and other base 24.
7+25+24= 56
56/2=28
28 units squared

<h3>Answer: 73</h3>
==================================================
Work Shown:
Check out the diagram below. Note the pair of alternate interior angles that are congruent (each 37 degrees). Then focus on triangle ABC. With the reference angle being at A, this means we use the tangent function because BC = x is the opposite side and AB = 97 is the adjacent side.
tan(angle) = opposite/adjacent
tan(A) = BC/AB
tan(37) = x/97
97*tan(37) = x
x = 97*tan(37)
x = 73.094742859971
For the last step, you'll need a calculator that can handle trig functions. Make sure the calculator is in degree mode. The result here is approximate. This rounds to 73 when rounding to the nearest whole number.
