Use a protractor to find the measure of each angle. write each angle and its measure in a box ordered by the measure of the angles from least to greatest.

Part 1) and Part 2) in the procedure

Step-by-step explanation:

step 1

Find the measures of angles

we know that

The sum of the angles A, B and C must be equal to 360 degrees

Using a protractor

The measures of angles are

∠A=140°

∠B=100°

∠C=120°

step 2

Ordered the measures of the angles from least to greatest

1) ∠B=100°

2) ∠C=120°

3) ∠A=140°

think about the doctor who treated the major and the speaker in the short story "in another country." put yourself in the shoes of the doctor, and based on what you read in the story, write what you think his thoughts about the major and the speaker would be. use the following vocabulary in your response and change the form of these words as needed: detached resign withered

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
