How many unique triangles can be made when one angle measures 90° and another angle is half that measure?

Mathematics

4 0

Answer:

Infinite number        

Step-by-step explanation:

we know that                      

If one angle is 90°, and another half of that, then it must be 45° and so the third angle is also 45°. (The sum of the internal angles of a triangle must be equal to 180 degrees)

Remember that                

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

therefore                    

There is an infinite number of unique triangle with these angles.

Triangle ABC is isosceles. Which equation can be used to find the degree measure of A
Hunter-Best [27]

The answer to that is x + x + 118 = 180

Still confused? I'll explain why:

A triangle all together equals 180 degrees, so if the other two angles equal each other then all you need to do is add them up on one side, subtract 180, and then divide the remainding number by 2 to get the answer for one of the identical angles.

Determine if the two functions f and g are inverses of each other
Margarita [4]

Answer:

Yes.

Step-by-step explanation:

f(g(x))

f(\frac{x-12}{9})  

( I will have to replace all x's in 9x+12 with (\frac{x-12}{9})

9(\frac{x-12}{9})+12

(x-12)+12

x-12+12

x+(-12+12)

x+0

x

So the answer is yes.

A local theme park found that if the price of admission was $12 per person, the attendance for the week was 2200. When the price
dolphi86 [110]

You have two points

(12,2200) and (10,3000) You have enough information to set up an equation.

x1 = 12

x2 = 10

y1 = 2200

y2 = 3000

The slope = (y2 - y1)/ (x2 - x1)

The slope = (3000 - 2200) / (10 - 12)

Slope = 800 / - 2

slope = - 400

So far what you have is y = - 400x + b

To get b just use one of the points.

(10,3000)

y = - 400x + b

3000 = -400*10 + b

3000 = - 4000 + b Add 4000 to both sides.

3000 + 4000 = b

b = 7000

Answer y = - 400x + 7000

What happens if you use (12,2200)

y = -400*12+ 7000

y = - 4800 + 7000

y = 2200 As it should.
