Please help
I have no idea how to do this

a. AED=130 degrees

b. DEB=50 degrees

Step-by-step explanation:

a. There are 360 degrees in a circle. AEC and DEB are equal. We can remove them from the original 360.

360-50-50=260

AED and CEB are equal. Divide the remaining 260 between them.

260/2=130

AED=130 degrees

b. we got the answer to this in the first question. DEB is equal to AEC.

DEB=50 degrees

It might help you to lay two pencils across each other like the lines in this problem are. Notice that when you "open" up one side, the other opens the same amount. Same if you "close" a side. Sisicors are also a great example of this. It'll help you visualize which angles will be equal.

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)
