4 0

Answer:

Don't know if there's some kind of a formula to solve this, but by just looking at the triangle we can see that the side c is the longest, so it would be 2, b is the shortest, so it would be the square root of 3 and 1 is left for a

The measure of and angle θ is 7pi/4. What is the measure of the reference angle and tan θ is?
Lynna [10]
Check the picture below.

recall that a reference angle, is the angle made with the x-axis, regardless of the Quadrant the terminal point is at.

what's its tangent?  well, you can check your Unit Circle, if you don't have one, you'd want to get one about now, you can search online for one, quite a few to get there, anyhow, at that point, the "x" and the "y" are the same value, and thus the tangent is 1.

Find cos (2 theta angle) if sin (theta angle) =4/5
nataly862011 [7]
Sin(theta) = 4/5,cos^{2} (theta)=1-( \frac{4}{5})^{2} = 1 -  \frac{16}{25} = \frac{9}{25} We will switch it to formula: cos(2 theta)=cos^{2} (theta)-sin^{2} (theta)= \frac{9}{25} - \frac{16}{25}=- \frac{7}{25}

1. what is the value of x <br> 2. find the values of x and y
jok3333 [9.3K]
1) its an iscoceles triangle so the two angles at the base are equal

180-18

= 162/2

x = 61 degrees

2) x is 90 degrees since its a right angle.

angle b is 47 as its an iscoceles triangle.

180 - 47 - 90
y = 43 degrees
