Question

6. what is the parimeter of triangle ABC
8. What is the value of x​

Answer 1

6. 20 8. 120

Explanation:

add the side measurements up of the triangle:

2+5+2+3+3+5=7+5+8=20

That shape where the x is a quadrilateral so is't interior angles must add to 360 so you have 90+90+60+x=360

Solving: 230+x=360

So x=360-240=120

Answer 2

Perimeter = 20 units

x = 120°

Explanation:

We are given a triangle ABC with known side lengths for all three sides and an inscribed circle.

We are to find the perimeter of triangle ABC and the value of x.

Perimeter of triangle ABC = 2 + 2 + 5 + 5 + 3 + 3 = 20 units

The kite shape at the end is a quadrilateral which has a sum of angles of 360 degrees.

Two out of four angles are right angles and one is 60 so we can find the value of x.

x = 360 - (90 + 90 + 60) = 120°
