Given: m∠B = 46°; m∠C = 45°; m∠R = 46°; m∠T = 89° Prove: △ABC ~ △TRS Triangles A B C and T R S are shown. Angles A B C and T R S
are 46 degrees. Angle B C A is 45 degrees. Angle R T S is 89 degrees. Melissa believes that the AA similarity theorem can prove that the triangles are similar. Which fact would be necessary in the proof? △ABC is an acute triangle. △TRS is larger than △ABC. The sum of the measures of the interior angles of a triangle is 180°. The sum of the side lengths of two sides of a triangle is greater than the third side length.
Umm..... according to what I know <span> </span><span>The ratio of the sides of a 30°-60°-90° triangle are: short leg : long leg : hypotenuse 1 : √3 : 2 </span><span> if the short leg is 7, the long leg is √3 times that: Answer: 7√3 ≈ 12.12 inches </span>
