45 degrees, 135 degrees.

Since the two adjacent angles of a parallelogram must add to 180 degrees, the two angles have to be 45 and 135 degrees respectively.

In any right angled triangle, for any angle:

- The sine of the angle = the length of the opposite side. the length of the hypotenuse.
- The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
- The tangent of the angle = the length of the opposite side. the length of the adjacent side.

I don't think you can figure out the area of this rhombus/parallelogram.

The area of a parallelogram is base, which we have, times height.

Picture the parallelogram with all the angles being 90 degrees. The area would be 54 square centimetres. Now imagine you can slide the top part of the parallelogram to the right, with the bottom fixed and all the corners on hinges. In theory, you can nearly slide the top down until it is just above the base. The area would approach zero, as the height of the parallelogram decreases.

Good luck,

Paul

122.9 degrees, 57.1 degrees, and 122.9 degrees.

Opposite one is 57.1 degrees, the other two are 122.9 degrees.

The opposite corners of a parallelogram are equal, so angle C would be 53.

You should be aware that the adjective **adjacent** has no absolute meaning. It is relative to the angle you are considering.

Let some angle A in a right triangle. Let H be the measure of the hypotenuse. Do not confuse it with some height.

cos(A)=(measure of leg adjacent to A)/H

H= (measure of leg adjacent to A) / cos(A)

However what you call the opposite angle (the other angle I presume), is the complementary of of angle A. Call it angle B

In terms of that second angle

**H=(measure of leg adjacent to A)/ sin(B)**

What is adjacent to angle A is opposite to the complementary of A.

I think you should work a little more on the meaning of the words**adjacent **and **opposite** until you understand that they are relative concepts. **They mean nothing until you spell out what angle you are looking at. **Without proper understanding of these two concepts you will not be able to use correctly that mnemonic device which you have mangled (BTW)

I do not know it what language you have transcribed the mnemonic , but in English the device is called**SOH- CAH-TOA **

**SOH** means: To calculate the **Sine of an angle** divide the measure of the leg **Opposite to the angle** by the measure of the **H**ypotenuse.

**CAH** means: To calculate the **Cosine of an angle **divide the measure of the **side Adjacent to the angle **by the measure of the **Hypotenuse.**

**TOA **means: To calculate the **Tangent of an angle **divide the measure of the side **Opposite to the angle** by the measure of the side **Adjacent to the angle**.

Let some angle A in a right triangle. Let H be the measure of the hypotenuse. Do not confuse it with some height.

cos(A)=(measure of leg adjacent to A)/H

H= (measure of leg adjacent to A) / cos(A)

The angles are right angles.

There are several ways of doing this.

Opposite 12 and hypotenuse 13, so the sine of the angle is 12/13. Press 1 2 / 1 3 = 2nd [SIN^-1]

Adjacent 5 and hypotenuse 13, so the cosine of angle is 5/13. Press 5 / 1 3 = 2nd [COS^-1]

Adjacent 5 and opposite 12, so the tangent of the angle is 12/5. Press 1 2 / 5 = 2nd [TAN^-1].

Opposite 12 and hypotenuse 13, so the sine of the angle is 12/13. Press 1 2 / 1 3 = 2nd [SIN^-1]

Adjacent 5 and hypotenuse 13, so the cosine of angle is 5/13. Press 5 / 1 3 = 2nd [COS^-1]

The tangent of an angle (in a right triangle) is defined to be the length of the side opposite the angle, divided by the length of the side adjacent to the angle (that is not the hypoteneuse). As the angle approaches 90 degrees, the length of the opposite side gets very large and the length of the adjacent side nears 0. At 90 degrees, the length of the adjacent side is 0, and division by 0 is not defined, so the tangent of 90 degrees is not defined.
