The second angle in a triangle is one third as large as the first the third angle is two thirds as large as the first angle find the angle measures?

Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.

What is angle of reference in trigonometry?

This is a VERY important question and I am glad you asked it. First you have to remember that in drawing angles we think of 4 quadrants. Think of the XY plane - the first quadrant is where BOTH X and Y are positive. In the 2nd quadrant the X is negative and the Y is positive. In the 3rd quadrant the X and the Y are negative. In the 4th quadrant the X is positive and the Y is negative. Normally when we draw an angle we draw an angle less than 90 degrees. However, we can draw any angle we want from 0 to 360. However that angle can be represented by an angle less than 90 degrees in a certain quadrant. Take an angle like 120 degrees. That angle is the same as a 60 degree angle in the 2nd quadrant. A 210 degree angle is the same as a 30 degree angle in the 3rd quadrant. A 359 degree angle is the same as a 1 degree angle in the 4th quadrant. Those smaller angles are reference angles. This explanation would be better if I could insert graphs. I have attached a link to a picture. Alpha is the angle and Beta is the reference angle.


What happens when light hits a new medium at an angle?

it refracts according to snell's law: sin(angle 1) x refractive index of 1st medium = sin(angle 2) x refractive index of 2nd medium. Cross multiply to solve.


How do you find what percent of 300 is 150?

In order to find percentage of 1st number out of 2nd number we divide the 1st number with 2nd number and multiply it with 100. In this case divide 150 by 300 first. Then multiply the quotient with 100. 150/300=0.50 0.50*100=50%

Why does Sine Theta equal Sine 180 minus Theta?

When you subtract theta from 180 ( if theta is between 90 degrees and 180 degrees) you will get the reference angle of theta; the results of sine theta and sine of its reference angle will be the same and only the sign will be different depends on which quadrant the angle is located. Ex. 150 degrees' reference angle will be 30 degrees (180-150) sin150=1/2 (2nd quadrant); sin30=1/2 (1st quadrant) 1st quadrant: all trig functions are positive 2nd: sine and csc are positive 3rd: tangent and cot are positive 4th: cosine and secant are positive
