Answer:

$perimeter= 5\sqrt{15} + 5\sqrt{5}$

Step-by-step explanation:

Given ,

A right angle triangle ΔABC with right angle at C and ∠A=30° and AC=5√5 units .

Let ∠A=A,∠B=B∠C=C and AC=b,BC=a,CA=b .

Implies perimeter of triangle = a+b+c .

now

$tanA=\frac{a}{b} \\\a=b*tanA\\a= 5\sqrt{5} *tan30^0\\a=\frac{5\sqrt{5}}{\sqrt{3}}$

and

$cosA=\frac{b}{c} \\\c=\frac{b}{cosA} \\c=\frac{10\sqrt{5}}{\sqrt{3} }$

implies ,

$perimeter = \frac{5\sqrt{5}}{\sqrt{3}} + 5\sqrt{5} +\frac{10\sqrt{5}}{\sqrt{3} }\\perimeter= 5\sqrt{15} + 5\sqrt{5}$

If x-y=10 and x+y=20 what is the answer for x^2-y^2?

Minchanka [31]

200 because 15 - 5 is 10 and 15+5 is 20. so 15 squared is 225 and 5 squared is 25 and 225-25 is 200

I need help <br><br> Evaluate functions from their graph

andreev551 [17]

Answer:

$g(7)=4$

Step-by-step explanation:

We look for where $x=7$ . The way you find the answer is first, find the point $(0, 7)$ . Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).

Using this method here, we see that $g(7)$ intersects our line at $(7, 4)$ , so $g(7)=4$ .
