The picture shows a triangular island:
a right triangle is shown with an acute angle equal to 55 degrees. the length of the side of the triangle opposite to the acute angle is r. the length of the side of the triangle adjacent to the acute angle is s. the length of the hypotenuse is q.
which expression shows the value of q?
r cos 55°
r sin 55°
s over sin 55 degrees
s over cos 55 degrees

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
