Let x be the measure of angle BAC. Since this is an isosceles triangle, the measure of BCA is equal to BAC. 

x+x+90 = 180

2x+90-90 = 180-90

2x = 90

2x/2 = 90/2

x = 45

The two angles BAC and BCA are each 45 degrees. This is a 45-45-90 triangle

The answers to part A and B are the same: 45 degrees

-------------------------------------------

For parts C and D, the answers are also the same as well. This is because AB = BC in this isosceles triangle

AC = AB*sqrt(2)

10 = x*sqrt(2)

10/sqrt(2) = x*sqrt(2)/sqrt(2)

x = 10/sqrt(2)

x = 10*(1/sqrt(2))

x = 10*(sqrt(2)/2)

x = 5*sqrt(2)

AB is exactly 5*sqrt(2) units long

AB is approximately 7.0710678 units long

AB = BC so BC is also approximately 7.0710678 units long

Which is the equation of a line that has a slope of -2/3 ans passes through the point (-3, -1)
kupik [55]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - \frac{2}{3}, hence

y = - \frac{2}{3} x + c ← is the partial equation

To find c substitute (- 3, - 1) into the partial equation

- 1 = 2 + c ⇒ c = - 1 - 2 = - 3

y = - \frac{2}{3} x - 3 ← is the equation of the line

By counting the table entries, we can see that there are 10 different options for a 3-topping pizza.

The different toppings ought on a pizza are:

As a general rule of thumb, I recommend selecting three to five toppings for each pizza you create.

Because mozzarella is a basic component of every pizza I prepare, it does not qualify as a topping.

Other cheeses that can be used as toppings are goat cheese, feta, and smoked gouda.

The most common supreme toppings are pepperoni, link, immature bell pepper, ebony olives, and red onions.

Sautéed mushrooms or even hot peppers are frequently incorporated.

Even though the sauce and cheese should almost always go on the bottom, the toppings themselves usually require the greatest attention.

Regardless of how many layers your pizza has, the top layer will receive the most heat.

Thus, by counting the table entries, we can see that there are 10 different options for a 3-topping pizza.
