Answer:
Step-by-step explanation:
To find the measure of angle x we use cosine
[tex] \cos( \alpha ) = \frac{adjacent}{hypotenuse} [/tex]
From the question
PO is the hypotenuse = 13
The adjacent is 12
Substitute the values into the above formula
That's
[tex] \cos(x) = \frac{12}{13} [/tex]
[tex]x = \cos^{ - 1} ( \frac{12}{13} ) [/tex]
x = 22.6198
We have the final answer as
Hope this helps you
Answer:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X. All of the angles of an equilateral triangle are equal.
