how is the volume of a solution used in calculating concentration?
Answer:
it is moved 7 to the left of the parent function
Step-by-step explanation:
Answer:
x = 13.9
Step-by-step explanation:
With respect to the angle shown, we have the hypotenuse (the side opposite the 90 degree angle) and we have the adjacent side (which is the side labeled x). thus we can use the ratio "cosine" to solve this.
<em>The ratio of cosine is defined as:</em>

Where adjacent and hypotenuse are the respective sides and
is the angle
<em>Thus, we can now write:</em>

The first answer choice is right, x = 13.9
An isosceles triangle is when 2 angles are the same measure. an triangles angle equal to 180 degrees. therefore angle A is 80 degrees as well as angle B equals 80 degrees. since the angles of a triangle equal to 180 you subtract the two known angles to find angle C. So 180-80-80 which equals to 20.
Therefore angle C=20 degrees
