Total frequencies = 30 + 90+ 14 + 32 = 166

Cat1 Gr1 = 30/166 = 0.18
Cat1 Gr2 = 90/166 = 0.54

Problem 1

<h3>Answer: choice B) They are supplementary angles</h3>

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

Explanation:

The two angles combine to form a straight angle (which is 180 degrees). Another term for these angles is "linear pair" since they form a straight line.

=================================================

Problem 2

<h3>Answer: choice B) x = 7</h3>

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

Explanation:

The diagonal is never used in this problem. For any rhombus, the four exterior sides are always the same length.

=================================================

Problem 3

<h3>Answer: Choice D) 62 degrees</h3>

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

Explanation:

We use the angle addition postulate. This allows us to combine angles BAC and CAD to form angle BAD.

(angle BAC)+(angle CAD) = angle BAD

30 + x = 92

x = 92-30

x = 62

angle CAD = 62

What are the coordinates of the circumcenter of this triangle?
Oduvanchick [21]

Answer:

The coordinates of the circumcenter of this triangle are (3,2)

Step-by-step explanation:

we know that

The circumcenter is the point where the perpendicular bisectors of a triangle intersect

we have the coordinates

A(-2,5),B(-2,-1),C(8,-1)

step 1

Find the midpoint AB

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M=(\frac{-2-2}{2},\frac{5-1}{2})

M_A_B=(-2,2)

step 2

Find the equation of the line perpendicular to the segment AB that passes through the point (-2,2)

Is a horizontal line (parallel to the x-axis)

y=2 -----> equation A

step 3

Find the midpoint BC

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M=(\frac{-2+8}{2},\frac{-1-1}{2})

M_B_C=(3,-1)

step 4

Find the equation of the line perpendicular to the segment BC that passes through the point (3,-1)

Is a vertical line (parallel to the y-axis)

x=3 -----> equation B

step 5

Find the circumcenter

The circumcenter is the intersection point between the equation A and equation B

y=2 -----> equation A

x=3 -----> equation B

The intersection point is (3,2)

therefore

The coordinates of the circumcenter of this triangle are (3,2)
