1) the value of x is 7
Explanation:
1) From the diagram, the angles with the red ink are equal.
SInce the two angles at the base are equal, we call the triangle an isosceles triangle.
This triangle have two sides and two angle equal.
As a result, the sides opposite the angles given in the triangle are equal to each other.
The sides opposite the angles are x and 7. So, x is equal to 7.
Hence, the value of x is 7
The same principle or procedure can be applied to question number 2.
