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}

The problem below has been solved incorrectly. Identify and explain the error.
mylen [45]

Answer:

If you look over the steps you can see that until 4x + x + 3 = 18, evertything is dandy. But the step after that 4x + x =21 seems a bit fishy.

Think about it they subtract 3 from both sides so the first side is correct

4x + x, but they added 3 to the other side:

(4x+x+3) - 3 = 18 - 3\\4x+x = 15

not

4x+x = 21

Then we solve for 4x + x = 15

5x = 15\\x = \frac{15}{5} \\x = 3

To solve for y we use :

y = x+3

y = 3+3 = 6

so (3,6) is the right answer
