Question

If Sides are 17 and 12cm one diagonal is 25cm .Find the value of x​

Answer 1

Answer:

15 cm

Step-by-step explanation:

Find the area of the one triangle using Heron Formula:

Area = √s(s - a)(s - b)(s - c)

Find s:

s = (12 + 25 + 17) ÷ 2

s = 27

Find area of the triangle:

Area = √27(27 - 12)(27 - 25)(27 - 17)

Area = √27(15)(2)(10)

Area = √8100

Area = 90 cm²

Find x:

Area of triangle = 1/2 x base x height

90 = 1/2(12)(x)

6x = 90

x = 15 cm

Answer: x = 15 cm
