I need to find x can someone please help

PIT_PIT [208]

Answer:

$\boxed{\boxed{\tt x=87^{\circ}}}$

Step-by-step explanation:

We know that a triangle has 3 sides, A triangle's interior angles add up to 180 degrees.

Now, let's write this as an equation:

$\tt x^{\circ}+37^{\circ}+56^{\circ}=180^{\circ}$

The missing angle is 180° minus the sum of the other two angles.

$\tt x^{\circ}=180^{\circ}-56^{\circ}-37^{\circ}$

Subtract the numbers:

$\tt 180^{\circ}-56^{\circ}-37^{\circ}=87^{\circ}$

$\tt x=87^{\circ}$
