Question

In a triangle the smallest side is 28m the largest side is 100m and the smallest angle is equal to the difference between the larger two angles.
a.56
b.96
c.90
d.86
with explanation​

Answer 1

Step-by-step explanation:

Let the angles A, B and C are in ascending order

A+B+C = 180

C- B =A

or, A+B = C

=> C = 90°

Hence, triangle is right angled.

=> b² = 100² - 28² = 128 × 72 = 64 × 144

or, b = 8 × 12 = 96
