Algebra!! In the triangle to the​ below, the measure of ∠A equals the measure of ∠B. Find the value of x.

x=21

Step-by-step explanation:

45=2x+3

Subtract 3 from both sides of the equation.

42=2x

Divide 2 from both sides of the equation.

21=x

Hope this helps!

x=21°

Step-by-step explanation:

Angle A = Angle B

Angle A = 45°

2x+3 =45°

To work out what x is, you would have to do inverse operations.

45-3=42°

2x=42°

42÷2=21° (We divide by 2 because, in algebra, whenever a number is next to a letter, it means times, so then we have to do the opposite and divide).

So, x=21°

Hope this helps :)

the answer to this question is in the pic

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
