<u>Answer</u>

D. Obtuse; 120°


<u>Explanation</u>

A protractor is a mathematical instrument that is used to measure angles.

Obtuse ⇒ Is an angle greater than 90° but less than 180°

Acute ⇒ Is an angle less than 90°.

∴  ∠GOF is and <em>obtuse angle</em>

   ∠GOF = 135 - 15

                 =<em> 120°</em>

Answer : D. Obtuse; 120°

The figure shows ∠GOF drawn with a protractor.

From the given figure

Angle G = 15 degrees

Angle F = 135 degrees

The difference between angle F  and angle G is the∠GOF

∠GOF = ∠F - ∠G = 135 - 15 = 120 degrees

When the angle is less than 90 degree then it is called as acute angle

When the angle is greater than 90 degree then it is called as obtuse angle

120 degree is greater than 90. so it is an obtuse angle

Find x and Y pls help
lisabon 2012 [21]

Answer:

Step-by-step explanation:

Comment

The angle supplementary to x and 3x are equal.

Supplementary angles = 180

Solution

x + 3x = 180

4x = 180                  Divide by 4

4x/4 = 180/4

x = 45

The angle supplementary to x is 3x

3x = 3*45

3x = 135

This angle is vertically opposite y. Vertically opposite angles are equal. So  y = 135

Answer

x = 45

y = 135

Q. Friday night’s hockey game was attended by 180 students. This is about 60 % of the school’s population. What is the total pop
OlgaM077 [116]

Answer:

The total population of the school is 300 students.

Step-by-step explanation:

Considering, we are working with percentage we can use the equation:

y = %x.

To fill in the equation you can use what you already know, 60% = 180

180 = 0.60x

To solve this, you can then divide both sides of the equation by 0.60. This will then give you your answer, 300 = x.

For checking, you can do 180 = 0.60(300) which will result in 180 = 180.
