Answer:
x = 13
Step-by-step explanation:
Since AD is a straight line, then the 3 angles at C sum to 180° , thus
∠ BCE = 180° - (90 + 64)° = 180° - 154° = 26°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABE is an exterior angle of the triangle, thus
3x = x + 26 ( subtract x from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
The HCF is the highest common factor of two numbers.
By definition, if two numbers are coprime, they have no common factors other than 1.
So, the highest (and only) common factor of two coprime numbers is 1.

Answer: {(5,0), (3,4)}
Step-by-step explanation:
You can apply the Substitution method:
- Solve for y from the second equation.
- Substitute into the first equation and solve for x.
Then:
(Remember that: 
)
Substitute the values obtained into one of the original equation and solve for y:
The solution set is: {(5,0), (3,4)}
