What is the measure of x in triangle ABC.

34 degrees

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

x + 123 + 23 = 180

x = 180 - 146

x = 34

34 degrees.

Step-by-step explanation:

The triangle is a 180 degrees angle.

so I subtracted 180 by 123 and got 57.

Then I took my 57 and subtracted it by 23.

That is how I got my answer! (34 degrees)

Hope this helps!

3075.1

Step-by-step explanation:

What is 19.1% of 16100?

Y is 19.1% of 16100

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 19.1% * 16100

Converting percent to decimal:

p = 19.1%/100 = 0.191

Y = 0.191 * 16100

Y = 3075.1
