Answer:
x=29
Step-by-step explanation:
We know for a fact that in a square:
- All of its angles have equal measure (90 degrees)
(e.g. Measure of Angle CAT, measure of Angle CST = 90 degrees)
Now that we know the facts, let's try to find x.
Now since we know that all the angles are equivalent to 90 degrees, we can say that Measurement of Angle SCA is 90 degrees. So:
[tex]90=3x+3[/tex]
Next, we'll simply just isolate the x:
[tex]90=3x+3\\90-3=3x+3-3\\87=3x\\\frac{87=3x}{3} \\29 = x[/tex]
