A right triangle has a leg with a length of 15 and a hypotenuse with a length of 15√2 Tameka believes it is a 45-45-90 triangle. Which of the following statements are correct? Select all that apply: A. The angle opposite to the side with length 15 measures 30 degrees
B. Tameka is correct. It is a 45-45-90 triangle
C. The measure of the remaining leg is 15√3
D. The measure of the remaining leg is also 15 E. The perimeter of the triangle is 45√2

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
