What is the value of y? Enter your answer in the box. y =

Olenka [21]

Answer:

$y=40\°$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles triangle

$AB=AC$

$5x=40\°$

$x=8\°$

The sum of the internal angles of a triangle is equal to $180\°$

Find the value of y

$(2y+20)\°+2(40\°)=180\°$

$2y=180\°-20\°-80\°$

$2y=80\°$

$y=40\°$

Can you help me please?

Daniel [21]

59pounds * 5days = 295pounds

6.95pounds * 3breakfasts = 20.85pounds

12.50pounds * 1eveningmeal = 12.50pounds

295pounds + 20.85pounds + 12.50pounds = 328.35pounds

Wrote out the units just for clarity! Liz payed 328.25 pounds altogether.

Find the slope of the line that passes through the points (0, -3) and (-4,1).

kozerog [31]

The formula for slope is $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

In this case:

$y_{2} = 1\\ y_{1} }= -3\\x_{2} = -4\\x_{1} = 0$

so...

$\frac{1 - (-3)}{-4 - 0}$

$\frac{4}{-4}$

-1 <<<The slope

Hope this helped!
