Help please I’m stuck

Mathematics
1 answer:
Liono4ka [1.6K]3 years ago
3 0

Answer:

10.5

Step-by-step explanation:

ΔXYZ is similar to ΔABC.  So the corresponding sides are proportional:

XY / AB = XZ / AC = YZ / BC

We want to find length AB, so we can either use the first proportion:

7 / k = 3 / 4.5

Or we can use the second proportion:

7 / k = 6 / 9

Either way, we'll get the same answer.  I'll use the second proportion.  Cross multiplying:

6k = 63

Dividing:

k = 10.5

Find the equation of the circle whose center and radius are given.<br> center ( 5.6), radius = 3
topjm [15]

Answer:

(x-5)² + (x-6)² = 9

Step-by-step explanation:

Remember that the equation of a circle is (x - h)² + (x - k)² = r², with <em>r </em>being the radius and <em>(h,k) </em>being the center point of a circle.

Since we are already given <em>r </em>and <em>(h,k)</em>, all we need to do is plug them into the formula to find our equation.
