<MLN = <JLK = 39 degrees (vertical angles are equal)

If JK ║MN then <M = <K = 39 degrees (Alternate interior angles are equal)

In a triangle, sum of all interior angles = 180

61 + 39 +3x + 5 = 180

Combine like terms

3x + 105 = 180

subtract 105 from both sides

3x = 75

divide both sides by 3

x = 25

Answer

x = 25

Find the real zeros of the trigonometric function on the interval 0 ≤ x < 2π

Romashka-Z-Leto [24]

F(x) = 4 [cos (x)]^2 - 3 = 0

4[cos(x)]^2 = 3

cos(x) = √3 / 2

That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.

Answer: x = 30 degrees and x = 330 degrees

During a fundraiser, Ms. Dawson’s class raised $560, which is 25% more than Mr. Casey’s class raised. How much money did Mr. Cas

evablogger [386]

Answer:

$420

Step-by-step explanation:

To work this out you would need to find the 25% decrease of 560. To do this you would first divide 25 by 100, which gives you 0.25. Then you would minus 0.25 from 1, which gives you 0.75. This is because when finding percentage decreases you would first have to convert it into a decimal. Then you would have to minus it from 1 , to make sure that it will be a 25% decrease not a 75% decrease. Then you would multiply 560 by 0.75, which gives you 420.

1) Divide 25 by 100.

$25/100=0.25$
