A^2 + b^2 = c^2
C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:
15^2 + b^2 = 17^2
225 + b^2 = 289
*-225 on both sides to get b by itself*
B^2 = 64
*to get rid of the ^2; you take the square root*
B = sqrt 64
B= 8 <— final answer
Result: 4020342569677260278
The answer is C. 75. Hope this helps.
∠MJK = 90 (It is a rectangle, so all its corners are right angles)
∠MJL = 90 - 27 = 63 (Complementary angles)
∠JLK = 180 - 90 = 27 = 63 (Sum of all angles in a triangle is 180)
∠KML = 27 (Isosceles triangle)
∠MNL = 180 - 27 - 27 - 126 (Sum of all angles in a triangle is 180)
Turn is into a decimal.............................
