Supplementary = 180 Degrees

So the measure of angle U + the measure of angle V = 180 Degrees

The measure of angle V is 3 times the measure of angle U, so

U+3U=180 Degrees, which can be written as 4U=180

You can find the value of U by dividing both sides by 4

U=180/4=45 Degrees

Since you are trying to find the value of x that makes U and V supplementary, you would sustitute the value of 45 Degrees that was calculated for U into the equation given for x.

45 Degrees = 3x

To solve you divide both sides by 3

x=45/3=15

x = 15 Degrees

5/8 people vote for blue

zhenek [66]

Answer:

The number of people vote for blue is 180.

Step-by-step explanation:

Let there are x numbers of total people.

So, $\frac{5}{8}$ of total people vote for blue i.e. $\frac{5x}{8}$ people vote for blue.

Now, the remaining number of people are $(x - \frac{5x}{8}) = \frac{3x}{8}$ .

If $\frac{5}{9}$ of the remaining people vote for green, then the number of people vote for green will be $(\frac{3x}{8} \times \frac{5}{9}) = \frac{5x}{24}$ .

Therefore, finally the remaining number of people is $(\frac{3x}{8} - \frac{5x}{24}) = \frac{x}{6}$ and they vote for red.

Now, $\frac{x}{6} = 48$ {Given}

⇒ x = 288

And the number of people vote for blue is $\frac{5x}{8} = \frac{5 \times 288}{8} = 180$ . (Answer)

Triangle abc has the angle mesausres shown. Which statement is true about the angles?

Umnica [9.8K]

Answer:

m∠A = 20°

Step-by-step explanation:

Given that the sum of the angles of any triangle is 180°, adding the expressions of each angle and setting them equal to 180° will give the value of 'x' and allow you to evaluate the angles.

2x + 5x + 11x = 180

18x = 180

18x/18 = 180/18 or x = 10

m∠A = 2x or 2(10) = 20°

m∠B = 5x or 5(10) = 50°

m∠C = 11x or 11(10) = 110°

Out of the choices given, the only one that is true is that m∠A = 20°.
