Answer:
The value of is equal to
Step-by-step explanation:
we know that
-----> by alternate exterior angles
solve for k
If a2 -2ab + b2 = 9 and a
then
[tex]\begin{gathered} (a-b)^2=9 \\ \sqrt{(a-b)^2}=\sqrt{9} \\ a-b=\pm3 \\ \\ aa-b=-3
Answer:
the giraffe gained 58 pounds each month.
Step-by-step explanation:
do 538-132 then do 406÷7. you will get 58.
hope this helps!
Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.
