Question

Solving for x, please answer quickly D:

Answer 1

Answer:

$x = 24$

Step-by-step explanation:

Sum of the interior angles in the triangle is 180 degrees

So,

$72 + 64 + 4x +20 = 180$

Now solve for x

$72 + 64 + 4x +20 = 180\\\\156 + x=180\\x=180-156\\x=24$

hope this helps you

please let me know if you have any other questions :-)

Answer 2

• We know, sum of all angles of a triangle is 180°.
• Therefore, by the problem

72 + 64 + (4x+20) = 180

or, 156 + 4x = 180

or, 4x = 180 - 156

or, 4x = 24

or, x = 24 ÷ 4 = 6

Your answer is 6.
