Answer:
a square
Step-by-step explanation: because a square has all four right angles and also a square can turn into a rectangle, but a rectangle can't turn into a square.
(x+5)(x-5) (cancels out the middle Nx factor)
(x+5)(x+5)
For example, the same angles could give you a triangle with sides 7-12-13, 35-60-65, or any other multiple. Find the third angle by subtracting from 180°. Then use the Law of Sines (28)★ twice to find the second and third sides. Use the Law of Cosines (31)★ to find the third side.Feb 19, 2018
Hi there!

From the unit circle, we can locate the two values of sine Ф (y-value of the coordinate) at which sin Ф = √3/2.
The two values are Ф = π/3 and 2π/3.
