Answer:

100 degrees

Step-by-step explanation:

The three angles inside a triangle always add up to 180

so, 180-43-57 is 80

But that's the angle inside the triangle. notice that that angle (ACD) and BCA make a straight line.  That means they add up to 180. Therefore, 180-80=100 degrees.

3y=24 solve by inspection
Ulleksa [173]

Explanation: Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a÷c=b÷c for c≠0

<u><em>First, you divide by 3 both sides of an equation.</em></u>

<u><em>3y/3=24/3</em></u>

<u><em>Then, simplify.</em></u>

<u><em>24/3=8</em></u>

<u><em>8*3=24</em></u>

<u><em>24/8=3</em></u>

<u><em>y=8 is the final answer.</em></u>

<u><em>Hope this helps!</em></u>

<u><em>Thanks!</em></u>

<u><em>Have a great day!</em></u>
