Answer:

Step-by-step explanation:

The angles 7x° and (x + 20)° are supplementary angles.

Supplementary angles add up to 180°.

Therefore we have the equation:

7x + (x + 20) = 180

7x + x + 20 = 180 <em>subtract 20 from both sides</em>

8x = 160 <em>divide both sides by 8</em>

x = 20

kow [346]

Answer:

∠ 2 = 45°

Step-by-step explanation:

∠ 1 and ∠ 2 are same- side interior angles and are supplementary, thus

∠ 2 = 180° - ∠ 1 = 180° - 135° = 45°

A high school has a total of 850 students. there are 60 more female students than there are make students?

Mrac [35]

Hey. Let me help you on this one.

Let's break this problem down so it's easier for us to comprehend it.

There are 850 students in the school, and the amount of female students equals to the amount of male students + sixty additional females.

Amount of students in school = 850 students

Male students = $X$

Female students = $X+60$

Let's form an equation so we can work with what we have.

$X+(X+60)=850$

Subtract 60 from both sides.

$X+X=790$

Simplify

$2X=790$

Divide both sides by 2.

$X=395$

Answer: There are 395 male students, and 455 female students.
