Find AD. Show how you got your answer.

stealth61 [152]

Notice the picture below
the AD line is a bisector, cutting the 36 degrees A in half,
18 and 18 degrees each half

notice the tickmarks, the triangle is an isosceles,
if those two sides are equal, so are the angles they make
down below with the base

now, the base is 8, AD is bisecting that too, to 4 and 4

now, using the Law of Sines

$\bf \textit{Law of sines}
\\ \quad \\
\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\
----------------------------\\\\
\cfrac{sin(18^o)}{4}=\cfrac{sin(72^o)}{\overline{AD}}\implies \overline{AD}=\cfrac{4\cdot sin(72^o)}{sin(18^o)}$

keep in mind, the angles are in degrees, so, when taking the sines, make sure your calculator is in Degree mode

Marcelo played a carnival games six times he spent three tokens to play each game and he won seven tokens each time write two di

Dimas [21]

Answer:

Step-by-step explanation:

let W represent the number of wins

and let P represent the number of plays

let T represent profit from each play.

from the question, Marcelo played 3 times, this means 3P can represent the first equation

He won 7 times, 7W can represent the second equation

and T which is profit is the difference between the number of tokens he won in each game and the number of tokens he spent to play each game.

Therefore, T = 7W - 3P

to get the total profit we will multiply T by the number of games played (in this case, 6)

this means that 6T = (7W - 3P) * 6

Since Marcelo spent and won tokens, the above expression of W and P can be expressed by a single variable. What this means is that, we can make 7W equal 7P or 3P equal 3W since we are dealing in the same item (tokens won and played)

profit per game (T) = 7P - 3P = 4P

total profit (for 6 games) = 4P * 6 =24

Second expression

we can also look at it from this angle;

-3 tokens+7 tokens = profit per game

profit per game for Marcelo = 4 tokens

total number of games = 6

total profit for Marcelo =6*4 = 24
