Step-by-step explanation:
It is an isosceles triangle , it has two equal angles both 55°.
All Isosceles triangles have two equal angles <em>a</em><em>n</em><em>d</em> two equal sides.
So in this case x +18 is equal to 3x, and to find x you will equal them to each other to create a linear equation and solve.
x + 18 = 3x
x - 3x = -18
-2x = -18
× = -18 / -2
× = 9 <em>(</em><em>a</em><em>n</em><em>s</em><em>)</em><em> </em>
Hope I was able to help. Good Luck :)))
The sum of angles of a triangle is 180°, so m∠K = 180° -45° -30° = 105°.
The Law of Sines tells you
... FL/sin(∠K) = FK/sin(∠L)
Solving for FL, we get
... FL = FK·sin(∠K)/sin(∠L)
... FL = a·sin(105°)/sin(30°) = a·sin(105°)/(1/2)
... FL = 2a·sin(105°) ≈ 1.93185a
line N has slope m = 
given a line with slope m then the slope of a line perpendicular to it is
= - 
thus line N has slope - 
=
Answer:
After 16 rounds the champion of Ping-Pong player can be determined.
Step-by-step explanation:
This is an example of geometric progression,
First term = 65,536
Now we need to find which term is 1 in this GP.
N th term of GP is given by
Substituting
Seventeenth term of this GP is 1.
That is after 16 rounds the champion of Ping-Pong player can be determined.
i think C but i dont know forsure
