Not sure if it’s correct but I had a similar question before
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
Given
y = x - 2
Multiply through by 9
9y = x - 18 ( add 18 to both sides )
x = 9y + 18
Change y back into terms of x, hence
(x) = 9x + 18
Answer:
x=69 degrees
Step-by-step explanation:
The whole angle is 90 degrees. So, you would need to subtract 90 minus 21 to get the degrees of angle x. So, you would get 69 degrees.
Hope I helped!! :)
Sorry if it's wrong! :(
Step-by-step explanation:
Angle XBC = 55 degrees because it is a corresponding angle with Angle AXC
and corresponding angles are equal or congruent.
Ok so angle XBC = 55 degrees and since this an isosceles triangle
XBC = XCB which means XCB = 55 degrees
Now to find angle BXC we know that all angles of a triangle add up to 180 degrees.
Angle XBC + Angle XCB + Angle BXC = 180 degrees
Let x represent angle BXC
55 + 55 + x = 180
110 + x = 180
x = 180 - 110
x = 70
∴ Angle BXC = 70 degrees
