Answer 2

Answer:

The value of x is 45°

Option C is correct.

Step-by-step explanation:

Given the figure of pentagon in which measure of interior angles are

∠1=90°, ∠2=148°, ∠3=(3x+10)°, ∠4=x°, ∠5=112°

we have to find the value of x

As the sum of the internal angles in a simple pentagon is 540°.

∴ ∠1+∠2+∠3+∠4+∠5=540°

90°+148°+(3x+10)°+x°+112°=540°

4x+360°=540°

4x=540-360

4x=180

x=45

Hence, the value of x is 45°

Option C is correct.
