If ray CE bisects angle DCF, and if angle DCE = x - 11, and angle ECF = 166 - 2x, then find ECF

a² + b²= c²

24² + 7² = c²

c= 25

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)

17

step-by-step explanation:
