Answer:

\cos P\approx 0.26

Step-by-step explanation:

In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.

In the given triangle, the adjacent side to angle P is marked as \sqrt{7} and the hypotenuse of the triangle is 10. Therefore, we have:

\cos P=\frac{\sqrt{7}}{10},\\\cos P=0.2645751311,\\\cos P \approx \boxed{0.26}

Answer:

\boxed {\boxed {\sf cos \  P \approx 0.26}}

Step-by-step explanation:

There are three main trigonometric functions: sine, cosine, and tangent.

We are asked to find the cosine of angle P. The cosine is the ratio of the adjacent side to the hypotenuse.

  • cos \theta = \frac{adjacent}{hypotenuse}

In this triangle, the side measuring √7 is the adjacent side because it is next to angle P. The side measuring 10 is the hypotenuse because it is opposite the right angle.

  • adjacent = √7
  • hypotenuse= 10

cos P= \frac{ \sqrt{7}}{10}

cos P=0.264575131106

Round to the nearest hundredth. The 4 in the thousandths place to the right ( 0.26<u>4</u>575131106) tells us to leave the 6 in the hundredths place.

cos P \approx 0.26

The cosine of angle P is approximately <u>0.26</u>

b) x|y
    2|1
    4|2
    6|3

Your graph for c would look like the attached picture

In every triangle,if one of those three angles has his measure more than 90°,then the triangle is optuse.
If all three angles are 60°,it means the triangle equiangular.

If one of those three angles is equal to 90°,the triangle is right.

If all the angles of the triangle have their measure less than 90°,the triangle is acute.

_____________________________________________________________

Your triangle has an angle bigger than 90°,it means the triangle is optuse.
