Answer:
[tex]\boxed{x\degree+63\degree=90\degree}[/tex]
Step-by-step explanation:
The symbol [tex]\boxed{}[/tex], is used to indicate a right angle.
This implies that, the [tex]x[/tex] degree angle and the [tex]63\degree[/tex] angle will add up to [tex]90\degree[/tex].
In other words, the two angles are complementary.
The equation that we can use to solve for [tex]x[/tex] is
[tex]x\degree+63\degree=90\degree[/tex]
When we solve for [tex]x[/tex], we get
[tex]x=90-63[/tex]
[tex]\Rightarrow x=27\degree[/tex]
