In a right-angled triangle, one of the angles is 60, the sum of the hypotenuse and the smaller leg is 45 m. Find the length of the hypotenuse.
The triangle is rectangular. If angle 1 is 60, then 2 is 30. Leg opposite an angle of 30 degrees = half the hypotenuse. He is also the smaller leg.
Let’s designate AB-hypotenuse, BC-smaller leg. AB + BC = 45
BC + 2BC = 45
3BC = 45
BC = 15
AB = 30
