Find the measures of the angles in each triangle <br> 2xº<br> 3x°<br> xº

snow_lady [41]

Answer:

x = 30°

The angles:

2x° = 60°
3x° = 90°
x° = 30°

Step-by-step explanation:

Hello!

The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.

Solve the equation:

2x° + 3x° + x° = 180°
6x° = 180°
x° = 30°

We can replace 30° for all the angles.

The measures are:

2(30°) = 60°
3(30°) = 90°
1(30°) = 30°

ricardo purchased a bunk bed for his children fora sale price of $276.25. The sale price was 65% of the original price. Calculat

nikklg [1K]

Use the formula S=P-PD

S is sale price, original price is P, and PD is discounted percent,

276.25=P-P(.65), I turned the percent into a decimal.

276.25=P(1-.65)

276.25=P(.35)

Now cross multiply.

$\frac{276.26}{.35}=\frac{P(.35)}{.35}\\\\P=\frac{276.26}{.35}=789.31$

Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)
