Q. QUESTIONSolve the right triangle.Round your answers to the nearest tenth.EXPLANATIONStart
Pythagorean Theorem for Hypotenuse: We need to know at least one side length and one non-right angle, or two side lengths to solve the triangle. Let's assume we know the lengths of the two legs, a and b, and we need to find the hypotenuse c and the angles.
Trigonometric Ratios for Angle A: Use the Pythagorean theorem to find the hypotenuse: c2=a2+b2. If a=3 and b=4, then c2=32+42=9+16=25. So, c=25=5.
Inverse Tangent Calculation: Now, let's find the angles. We can use trigonometric ratios. For angle A, opposite side is a and adjacent side is b. So, tan(A)=adjacentopposite=ba=43.
Angle B Calculation: To find angle A, we take the inverse tangent of 43. A=tan−1(43). Let's say this gives us A=36.9 degrees, rounded to the nearest tenth.
Angle Sum Verification: Since the sum of angles in a triangle is 180 degrees and one angle is 90 degrees (right angle), the other angle B can be found by subtracting angle A and the right angle from 180. B=180−90−A. B=180−90−36.9=53.1 degrees.

B=180−90−A. B=180−90−36.9=53.1 degrees.Check if the angles add up to 180 degrees. A+B+90=36.9+53.1+90=180 degrees. Looks good.
