Answer:
8 and 6
Step-by-step explanation:
8*8=64
6*6=36
36+64=100
Answer:
x = 11
Step-by-step explanation:
- Vertically opposite angles are equal
- Angles around a point add up to 360°
Therefore, 



Answer: x=40°
Step-by-step explanation:
The two triangles are congruent (I think it’s called the interior angle proof) so the bottom right angle is also 65°. All angles in a Triangle equal 180°, so 180-(75+65)=40
Answer:

Step-by-step explanation:
2)
a) elimination method
b) substitution method
c) substitution method
For the first part we can elimate the y variable by subtracting the equations. We can then find the value of x.
For the second part we can substitute y as 2x+5 in the second equation and solve for x.
For the third part we can substitute y as 4x+3 in the first equation and solve for x.
