So,

Notice that there is a triangle with two of the angles given.  We know that the sum of any triangle's angles will always be 180°.  Thus, we can subtract the two given angles from 180, and that will give us the measure of angle ABC.

180 - 20 - 25 = 160 - 25 = 135

The measure of angle ABC is 135°.

The correct option is D.

Gareth 30 students in a class and the ratio of boys to girls in the class is 2:3 calculate the number of goals
pishuonlain [190]

Answer:

<em>There are 12 boys and 18 girls</em>

Step-by-step explanation:

<u>Equations</u>

There are 30 students in a class. Let's call:

x = number of boys

Since the sum of boys and girls is 30:

30 - x = number of girls

The ratio of boys to girls is 2:3, thus:

\displaystyle \frac{x}{30-x}=\frac{2}{3}

Crossing denominators:

3x = 2(30 - x)

Operating the parentheses:

3x = 60 - 2x

Adding 2x:

5x = 60

Dividing by 5:

x = 60/5 = 12

x = 12

There are 12 boys and 30-12=18 girls
