Question

Determine the value of x

Answer 1

x = 17

Explanation:

`\because\triangle IJK \cong \triangle PQR.....(given)\\\therefore \angle I \cong \angle P....(cact)\\\therefore m\angle I = m\angle P\\\therefore 3x+4 = 72-x\\\therefore 3x+x = 72-4\\\therefore 4x = 68\\\therefore x = (68)/(4)\\\therefore x = 17`

Answer 2

3x+4=72-x (congruent triangle side are equal)

3x+x=72-4

4x=68

X=68/4

therefore,X=17 ans
