In AOPQ, o = 700 cm, p = 840 cm and q=620 cm. Find the measure of _P to the<br> nearest degree

Westkost [7]

Given:

In triangle OPQ, o = 700 cm, p = 840 cm and q=620 cm.

To find:

The measure of angle P.

Solution:

According to the Law of Cosines:

$\cos A=\dfrac{b^2+c^2-a^2}{2bc}$

Using Law of Cosines in triangle OPQ, we get

$\cos P=\dfrac{o^2+q^2-p^2}{2oq}$

$\cos P=\dfrac{(700)^2+(620)^2-(840)^2}{2(700)(620)}$

$\cos P=\dfrac{490000+384400-705600}{868000}$

$\cos P=\dfrac{168800}{868000}$

On further simplification, we get

$\cos P=0.19447$

$P=\cos^{-1}(0.19447)$

$P=78.786236$

$P\approx 79$

Therefore, the measure of angle P is 79 degrees.

Help if cool | will give brainliest

iogann1982 [59]

Step-by-step explanation:

distance walked by him = 1/ 3 miles

time taken in doing so = 3/ 4 hrs.

$speed \: acquired \: by \: him \: = \frac{distance}{time}$

$= \frac{ \frac{1}{3} }{ \frac{3}{4} } \\ = \frac{ 1}{3} \times \frac{4}{3} \\ = \frac{4}{9} \: miles \: hr^{ - 1}$
