Answer the questions to find the measures of ∠2 and ∠3.

1. What is the measure of ∠4? Explain how you know.

2. What is the sum of the measures of the angles in a triangle?

3. ∠1 is in a triangle with ∠4 and a 53° angle. What is the sum of the measures of those two angles?

4. What is the measure of ∠1? Explain.

5. Find the measure of ∠2. Explain how you found its measure.

6. What is the measure of ∠3? Explain.

1. The measure of angle 4 is equal to 90 degrees.

2. The sum of the angles in every triangle is equal to 180 degrees.

3. The sum of angle 4 and 53 degree angle is 143.

4. The measure of angle one is 37 degrees. For this one you add up angle 4, or 90 degrees and the 53 degree angle. 90+53=143, next you subtract 143 from 180 to get the last angle.

5. The measure of angle 2 is equal to 120 degrees. I found this because if you look at the triangle, angle 3 and the 30 degree angle below it look the same, so you add those together to get 60, then you subtract 60 from the sum of all the angle or 180. 180-6=120

6. Angle 3 is equal to 30 degrees. This is because as i said above, angle 3 is the same as the 30 degree angle shown below, also if you add angle two and the 30 degree angle and subtract that sum from 180, it is equal to 30.

Big question lol. Hope this helps.

NEED HELP ASAP 27 hundredths is written this way: 0.27. Which scale shows 0.27 kilogram?

a) If x=7a-b (7 power a-b) and y = 7b-, show that xy = 1.

b) If a = 2 and b = 1, show that (a + b)² = a² + 2ab + b²

c) If a = 5 and b = 3, show that (a - b)² = a² - 2ab + b²

Please help me solve this. Thank you​

A student is measuring the length of an icicle, y, every hour, x. The icicle is currently 13 inches long and is melting at a rate of 0.4 inches per hour. Find and interpret the slope for this relationship.

0.4; for every additional hour, the length of the icicle increases by 0.4 inches
−0.4; for every additional hour, the length of the icicle decreases by 0.4 inches
13; the length of the icicle when the student first measures it
−13; the length of the icicle when the student first measures it

A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!

Can you solve this for me? Thank you! :>

Think of an activity that you enjoy or are interested in. Some examples are reading, swimming, or leveling up your gaming character. Use your activity to work through the following problems:

Create a scenario that leads to an inequality of the form ax + b > c. You can use any of the inequality symbols (>, ≥, <, ≤) in your inequality. For this step, just write the word problem.
Write the inequality and show all work to solve the inequality.
Graph the solution to your inequality on a number line.
Explain what your solution means in the context of the problem.

PLEASE HELPPPPPPP
The weather report says the temperature is 20°C and will drop 5°C per hour for the next 6 hours. Daryl plans to be gone for at least 6 hours, and he has a plant outside. If he wants the plant to remain in temperatures above –10°C, should Daryl move his plant to a warmer location before leaving?

An inequality to model the problem is
20+5x>-10
20-5x>-10
20-5x<-10
20+5x<-10
The solution is
x<3/4
x<2
x<6
x>6
