check the picture below.


the outside line touching the circle, the 13.5 one, we don't have enough info to say is a secant, like the 8.45 one, so the 13.5 is a tangent line, which is touching the radius chord, and the point of tangency is always a right angle.

Assuming that the side of the triangle marked 13.5 is tangent to the circle, the there's a right angle where the radius meets the tangent segment. The triangle is then a right triangle and the Pythagorean Theorem applies.

What is the height of the tv and is it square inches or inches ??
fiasKO [112]
To find the height of the TV you first need to realize that the question is giving you dimensions for a triangle. 

Every triangle has a hypotenuse and two sides. To find the hypotenuse you square both sides, add them, and then square root. So to find one of the sides you get the hypotenuse, square it, and subtract the square length of the given side. 

The equation is 25^2-20^2.
Which if simplified is 625-400, the then solution is going to be 225. 
You next will square root 225, 225^(1/2). Which your answer should be 15 inches for the missing side length.

Answer:

Yes

Step-by-step explanation:

As long as any two numbers added are greater than the number not chosen they can make a triangle

2+7= 9     9 is greater than 8

8+2= 10    10 is greater than 7

7+8= 15 .  15 is greater than 2

Write the equation of the line containing the points (3, 6) and (7, - 2) in standard form.
Rama09 [41]

Answer:

y = mx + c \\ 6 = 3m + c...(1) \\  - 2 = 7m + c...(2) \\ subtract \: (2) - (1) \\ 4m =  - 8 \\  \therefore \: m  = - 2 \: sub \: in \: (1) \\ 6 = 3( - 2) + c \\ \therefore \: c  = 12 \\  \boxed{y =  - 2x + 12}
