Question

Find the missing angle

Answer 1

a=45 degrees

Explanation:

So we know in a triangle there is 180 degrees.

1 of the angle we know is 90 degree

angle B is the same as angle A

So the equation is 90+2a=180 solve it u get 45 degree

Answer 2

• 
  `\sf BA=√(18)`

Explanation:

`\sf (BA)^2=(BC)^2+(AC)^2`

`\sf (BA)^2=(3)^2+(3)^2`

`\sf (BA)^2=√(9+9)`

`(\sf BA)^2=√(18)`

`\sf BA=√(18)`
