Answer:
d. 2√286
Step-by-step explanation:
To find x, we need to use pythagoras theory:
a² + b² = c², where c is the hypotenuse or the slant of the triangle
Substitute (plug in) in the values:
x² + 15² = 37²
Simplify:
x² + 225 = 1369
x² = 1369 - 225 (I subtracted 225 from both sides)
x² = 1144
x = √1144 = 2√286
