Answer:
15
Step-by-step explanation:
since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as
13+x+4x+2=90
add the x variables together and the constants separately
15+5x=90
then subtract 15 from both sides.
15+5x=90
-15 -15
5x=75
then divide 5 from both sides.
75/5= 15
so x is 15 :).
Answer:
11 units
Step-by-step explanation:
To calculate CD use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(- 4, 6) and (x₂, y₂ ) = D(- 4, - 5)
CD =

= 11
Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
