Answer:
Below
Step-by-step explanation:
You can use sine law to solve this : sina / A = sinb / B
We will first find side x
We know that since this is a special triangle that side will = 28, but we can prove this mathematically :
sin(45) / 28 = sin(45) / x
= 28 sin(45) / sin(45)
x = 28
Now to find side r just use Pythagorean theorem a^2 + b^2 = c^2 :
c^2 = 28^2 + 28^2
= 1568
Square root this number
r = 39.597
The just round to however your teacher wants
If you didn't already know about special triangles, an isosceles right triangle like this one has a ratio which is the two legs will equal each other, while the hypotenuse is √2a . You could have also used this to solve.
Hope this helps! Best of luck.
Answer:
(-3, -2)
Step-by-step explanation:
The transformation (x, y) ⇒ (y, -x) represents a rotation of 270° CCW about the origin (or 90° CW).
This transformation maps the point Q(2, -3) to Q'(-3, -2).
