Given M ,N find the value of x

Answers

Answer:

x = 59 , y = 44

Step-by-step explanation:

(2x + 18) and (x - 15) are adjacent angles on a straight line and sum to 180°

2x + 18 + x - 15 = 180 , collect like terms

3x + 3 = 180 ( subtract 3 from both sides )

3x = 177 ( divide both sides by 3 )

x = 59

Then

x - 15 = 59 - 15 = 44

y and (x - 15) are corresponding angles and are congruent , then

y = 44

can someone please help me with how to find the perimeter and area of this

Answers

Answer:

Perimeter = 68ft

Area = 289ft²

Step-by-step explanation:

The lines on each side mean that they are all the same length - this shape is a square.

To find the perimeter, do 17 + 17 + 17 + 17 or 17 × 4. This gives you 68ft.

To find the area, you multiply the length and width → 17 × 17 = 289ft²

Is the relationship shown by the data linear? If so, model the data with an equation.

A. The relationship is linear; y + 2= -5/4(x + 9).
B. The relationship is not linear.
C. The relationship is linear; y + 2= 4/5(x + 9).
D. The relationship is linear; y + 9= -4/5(x + 2).

Answers

Answer:

D. The relationship is linear; y + 9= -4/5(x + 2).

Step-by-step explanation:

yes its linear because the x values increase by a constant value 4 and the y values by a constant value -5.

one general form for a linear equation is

y - y1 = m(x - x1)      m = slope and (x1,y1) is a point on the line

from the data the slope iis  (-7-(-2)) /  (-5-(-9)  =  -5 / 4

so using the point (3, -17):-

y - (-17) = (-5/4) ( x - 3)

y + 17 = -5x/4 + 15/4

4y + 68 = -5x + 15

4y = -5x - 53  

thats the equation of the line

(ii) Explain why a+b+c= 235°
This is a cornet maths question. How do I solve it

Answers

Answer:

Where is the image?

Step-by-step explanation:

Tell me in comments

The equation a + b + c = 235 is true because a = c = 55° and b = 125°

How to prove that a + b + c = 235?

The angle a and 125° are on the same straight line.

So, we have:

a + 125° = 180°

Subtract 125 from both sides

a = 55°

The angle b and 125° are vertical angles

So, we have:

b = 125°

The angle a and angle a are vertical angles

So, we have:

c = a

This gives

c = 55°

Add the three angles

a + b + c = 55° + 125° + 55°

Evaluate the sum

a + b + c = 235°

Hence, it is true that a + b + c = 235°
