The sum of 4 and y divided by 5 equal to 9. Find the value of y.​<br>pls a better solution
rosijanka [135]

Answer:

y=41

Step-by-step explanation:

Let us start by writing an equation. <em>4 plus y divided by 5 equals to 9</em> :

\frac{4+y}{5}=9

Great! Now let us solve for the variable, <em>y</em>, by isolating the terms:

4+y=45\\y=41

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}&#10;\\ \quad \\&#10;\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\&#10;----------------------------\\\\&#10;\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
