Can someone please check my work?
- ABCD is equal to QRST.
- The measure of angle A is x-10 & the measure of angle Q is 2x-30 -- What is the Measure of angle A??

I got 20 becuase I think that A and Q would be equal. and 20-x is 10 as is 2x-30.

Assuming A = Q, you can set the equations equal to each other.
x-10 = 2x - 30
Subtract x from each side and add 30 to each side.
20 = x

Now, to get the angle of A, you have to plug 20 into the equation for A.
A = x-10
A = 20-10
A = 10
