A triangle's angles all add up to 180 degrees. Since it's stated in the answer that angle C is a right angle, which is 90 degrees, and the other two angles are equal, the other two must be 45 degrees.
The answer is B.

The best and most correct answer among the choices provided by your question is the second choice or letter A. The measures of both angles would be 45 degrees.

If A = B = 45 degrees
Therefore, sin (45) = sin (45) = sqrt(2)/2
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

If the diagonals of a quadrilateral bisect all the angles, then it's a rhombus, converse of a property. If the diagonals of a quadrilateral are perpendicular bisectors of each other, then it's a rhombus, converse of a property.

Lee is thinking of two Numbers,the product is 18. the quotient is 2

defon

X, y - the numbers

The product is 18.
$xy=18$

The quotient is 2.
$\frac{x}{y}=2 \ \ \ |\times y \\
x=2y$

Substitute 2y for x in the 1st equation:
$2y \times y=18 \\
2y^2=18 \ \ \ |\div 2 \\
y^2=9 \\
y=\pm \sqrt{9} \\
y=3 \ \lor \ y=-3 \\ \\
x=2y \\
x=2 \times 3 \ \lor \ x=2 \times (-3) \\
x=6 \ \lor \ x=-6 \\ \\
(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)$

The numbers are 6 and 3 or -6 and -3.
