Use pythagorean theoram(idk the spelling). Basically a^2+b^=c^2 where a and b are the legs of the triangle and c is the hypotenuse. so if we solve it we get 6^2 + (7/4)^2 = c^2
<span>Triangle PQR is similar to triangle TSR because measure of angle 3 equals measure of angle 4 and measure of angle 1 equals measure of angle 5</span>
