Since we know that the x-axis is 180 degrees and the square looking symbol represents that it is 90 degrees, we know that the other side has to also equal 90 degrees since 180-90=90.
To find the x, we need to subtract 90 from 61, which would give us 90-61 = 29.
X+61=90 X=29 Everytime it shows the x in the graph it means you have to and the number by x. Than there’s a 90 degree square which now you know that x+61 equals 90 than you solve for x
