87 degrees is the right answer
PIT_PIT [208]2 years ago
4 0

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}

Ashely is making $500 a week at her job. She receives a 20% pay raise. A year later she takes a 5% pay cut. How much money does
zheka24 [161]

Answer:

<em>$570 a week</em>

Step-by-step explanation:

<u>Percentage Calculations </u>

One tricky fact about percentages is that they are usually performed over the last computed quantity. It makes them non-additive. For example, a raise of 10% followed by a 10% some time later, is NOT a 20% of total raise

The question states Ashely is making $500 a week at her job and that she receives a 20% pay raise. After that raise she will make

\$500*(1+20/100)=\$500(1.2)=\$600 \text{ a week}

A year later she takes a 5% pay cut. We must be careful to take that percentage from the last earnings. She now makes

\$600(1-5/100)=\$600(0.95)=\$570\ a\ week
