The formula for distance is :
d = √(x₂-x₁)²+(y₂-y₁)²
Let the point (10;10) be (x₂; y₂) , and let the point (4;10) be (x₁;y₁).
So it would look like this -
d = √(10-4)² + (10-10)²
d = √(6)²+ (0)
d = √36
d = 6 units
Hope this helped~
Answer:
∠ Y = 45°, ∠ X = 135°
Step-by-step explanation:
Since the 2 angles are supplementary, then
X + Y = 180 ← substitute X = 3Y
3Y + Y = 180, that is
4Y = 180 ( divide both sides by 4 )
Y = 45
and
X + Y = 180, so
X + 45 = 180 ( subtract 45 from both sides )
X = 135
Thus
∠ X = 135° and ∠ Y = 45°

Answer:
5
Step-by-step explanation:
You can express this as a system of equations:
x in this instance will be her present age.
x + 8 = 2x + 3
simply solve for x after this by subtracting three and x from both sides, and you’ll find that x is 5.
