Answer:
10.7
Step-by-step explanation:
You set up the proportion like this:

When you solve for x you get

x=10.7 rounded to the nearest tenth
Answer: x= 98°
Step-by-step explanation:
Concept:
Here, we need to know the concept of the "Exterior Angle theorem"
The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two opposite angles of the triangle.
If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
x = 53 + 45 = 98°

Center of circle is ( 1, 0).
Slope of normal passing though ( 1, 0 ) and ( 2, -5 ) is :

So, slope of tangent will be :

Equation of tangent :

Hence, this is the required solution.

Difference/original
783 - 540 = 243
243/540 = 0.45
0.45 * 100 = 45
45% = increased percentage
