Find the measure of angle A. This is for my math class, and I’ve been stuck on this for a while. Please help!

x = 7.6°, so A = 18.8°

Step-by-step explanation:

What we need to know in order to utilize algebra is the total sum of all triangle's angle. It's 180°. So, we can write

25 + 17x - 1 + 3x - 4 = 180

20x + 28 = 180

20x = 152

x = 7.6°

Now what you need to do is substitute 7.6° into each expression 17x - 1 and 3x - 4.

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.
