When you draw a diagonal line from Y to W, you will create two congruent triangles.

Each of these triangles will have three sides of different lengths, making them scalene triangles.

In each of these triangles, there will be one 90° angle, right angle, and two acute angles (less than 90°). This would classify these triangles as right triangles based on the angles.

Both triangles are right, scalene triangles.

In ΔNOP, the measure of ∠P=90°, NP = 12, PO = 35, and ON = 37. What ratio represents the cosine of ∠O?
Oxana [17]

Answer:

35/37

Step-by-step explanation:

In this question, we are to calculate the ratio that represents the cosine of angle O

Firstly, please check attachment for diagram of the triangle.

Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse

The hypotenuse is the longest length which is 37 which represents the length ON

The side adjacent to angle O is the side OP which is 35

Thus, the ratio representing the cosine of angle O is 35/37

It took Daniela 3/4 of an hour to do her mouth and work it took her 4/5 of an hour to do the English homework how much more time
Dmitrij [34]

Answer:

Daniela spent 1/20 of an hour longer on her English homework than her Math homework.

Step-by-step explanation:

I think what your asking is how much longer Daniela took on her English homework then her math homework. If that's what your asking, you need to subtract 3/4 from 4/5.

First, the denominators need to be the same (meaning we have to multiply them):

4/5 * 4 = 16/20

3/4 * 5 = 15/20  

Finally, we subtract the two fractions:

16/20 - 15/20 = 1/20
