Find c in the pic below
Fiesta28 [93]

Answer:

A

Step-by-step explanation:

To find the angle inside the triangle (to the right side of 90 degree angle), we first have to find the adjacent angle (below it).

Angle 122 and that adjacent angle is same (parallel lines cut by transversal -- they are corresponding angles).

So that angle is 122.

The inside triangle angle (what we want) is adjacent to 122, so we can write:

Angle + 122 = 180  [straight angle/straight line is 180 degrees]

Solving for that angle, we have:

Angle = 180 - 122 = 58

Now, looking at the triangle, Side C is "opposite" of 58°  and side "20" is the side that is "hypotenuse" [side opposite of 90 degree angle is hypotenuse).

<em>Which trig ratio relates "opposite" and "hypotenuse"??</em>

<em>Yes, it is SIN. Thus we can write:</em>

<em>Sin(58)=\frac{Opposite}{Hypotenuse}=\frac{C}{20}</em>

<em />

<em>We can now solve for C:</em>

<em>Sin(58)=\frac{C}{20}\\C=20*Sin(58)\\C=16.96</em>

<em />

<em>Correct answer is A</em>

Triangle RST was dilated by a scale factor of . The image, triangle R'S'T', is an isosceles triangle, with each leg measuring 8
Alik [6]
<span>Triangle RST was dilated by a scale factor of 1/2

Given: </span><span>triangle R'S'T', is an isosceles triangle, with each leg measuring 8 units. 

Pre-image: 
measure of pre-image * scale factor = measure of resulting image

measure of pre-image = measure of resulting image / scale factor

measure of pre-image = 8 / 1/2
measure of pre-image = 8 * 2/1 

measure of pre-image = 16 units.</span>
