30 70 80 how many triangles cant you construct with these measurments
Alinara [238K]

Answer:

One triangle can be constructed.

Step-by-step explanation:

 Recap that all the interior angles in a triangle add up to 180. With the given measurements of the angles, 70 plus 80 plus 30 equals 180. Each triangle has the sum of 180 degrees. Therefore, there can only be one triangle that can be constructed. I think you were suppose to put can, not can't. Hope this helps!

Evaluate inverse functions <br><br> Find the following values f^-1(f(3.14)) <br> F(f(-7))
Margaret [11]

Answer:

1. 3.14

Step-by-step explanation:

If we have

f {}^{ - 1} (f(x)

That just equals

x

For example, consider function

f(x) = 2 {}^{x}

The inverse of that function is

y = 2 {}^{x}

x = 2 {}^{y}

log_{2}(x)  =  log_{2}(2 {}^{y} )

log_{2}(x)  = y

So

f {}^{ - 1} (x) =  log_{2}(x)

If we compose the function, f(x) into f^-1(x).

We get

log_{2}(2 {}^{x})  = x

That proof of that.

1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14

2. We first find f(-7) which is -12,

We then find f(-12)= 5 so the answer here is 5.
