Answer:

r=-3 FALSE

m<XYQ=7 TRUE

r=4 TRUE

Ray YQ bisects angle XYZ TRUE

Step-by-step explanation:

2r-1+3r-5=3r+2

5r-6=3r+2

2r=8

r=4

------------------------

r=-3 FALSE

m<XYQ=7 TRUE (XYQ=2r-1=2(4)-1=8-1=7)

r=4 TRUE

Ray YQ bisects angle XYZ TRUE  (ZYQ=3r-5=3(4)-5=12-5=7.  Both XYQ and ZYQ=7, so ray YQ is the bisector)

I don't know what the 10 is for in your question.

A circle has a radius of 98 units and is centered at (5.9,6.7) write the equation of the circle
Hoochie [10]

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

radius = √98

center = (5.9,6.7)

equation of the circle​ = ?

Step 02:

Equation of the circle​

(x - a) ² + (y - b) ² = r ²

(a , b) = center

(x - 5.9) ² + (y - 6.7) ² = (√98) ²

(x - 5.9) ² + (y - 6.7) ² = 98

The answer is:

(x - 5.9) ² + (y - 6.7) ² = 98
