(a) the given triangle is a isosceles triangle. The two base (non-congruent side) angles (in this case, ∠XYW & ∠XWY) will have the same measurements.

It is given that m∠XYW = 70°, therefore, m∠XWY is also 70°.

Subtract 180 from the two 70° to get m∠X:

180 - (70 + 70) = 180 - 140 = 40°

m∠X = 40° is your answer.

The given triangle is a equilateral triangle (All sides are congruent). If all sides are congruent, it is a equilateral triangle, and if it is a equilateral triangle, then all measurements of the inside angles are the same, 60°

m∠V = 60°

Which of the following is the function of f(x)?

Natasha2012 [34]

Answer:

f(x) = 8(x-3)

Step-by-step explanation:

F^ -1 ( x) = x/8 +3

Let y = x/8+3

To find the inverse

Exchange x and y

x = y/8+3

Solve for y

x-3 = y/8+3-3

x-3 = y/8

Multiply each side by 8

8(x-3) = y/8 * 8

8(x-3) = y

The inverse of the inverse is the function so

f(x) = 8(x-3)

the sum of two consecutive integers is -49 write an equation that models this situation and find the values of the two integers

hodyreva [135]

Х is the first integer
(x+1) is the second integer

x + x + 1 = -49
2x + 1 = - 49
2x = -49 - 1
2x = -50
x = -25 first integer
-25 + 1 = -24 second integer

Answer: -25 and -24

1.In the diagram of circle M shown, various points are located on the circle as shown.   a) List three segments that are radii o

dalvyx [7]

Answer:

(a)|MA|, |MB| and |MC|

(b) |BD|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

Definition

A radius is a line drawn from the center of a circle to its circumference.
A segment is a line that connects two points.
A diameter is a chord which passes through the center of the circle.
A chord is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|
