Mashcka [7]

Answer:

<em>( x = 17° )</em>

Step-by-step explanation:

Consider the following steps;

m< ZYW = 2x - Given,\\m< YXW = ( 3x - 5 ) - Given,\\m< XYW = 90 - Given,\\\\m< YXW + m< XYW + m< YWX = 180 - Sum of Angles in Triangle,\\( 3x - 5 ) + 90 + m< YWX = 180,\\3x - 5 + 90 + m< YWX = 180,\\3x - 5 + m< YWX = 90,\\m< YWX = 90 - 3x - 5,\\m< YWX = 85 - 3x,\\\\m< ZYW = m< YWX - Alternate Interior Angles,\\2x = 85 - 3x,\\5x = 85,\\Conclusion ; ( x = 17 degrees )

<em>Solution ; ( x = 17° )</em>

A line passes through the point (-7,8) and has a slope of 1
Mila [183]

Answer:

y - 8 = x + 7

Step-by-step explanation:

To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).

y - y_1 = m(x-x_1)\\y - 8 = 1(x --7)\\y - 8 = 1(x + 7)\\y - 8 = x+7

x= -0.25 and 1.25

x = -0.5 and  1.5

x = 0 and 1

x = -0.375 and 1.625

Step-by-step explanation:

Given equation of the curve is

y = 4x^2 -4x-1

(i)

First equation 4x^2 -4x-1 =0

Here y = 0

In  x-axis the value of y = 0

The graph cuts the x-axis at(-0.25,0) and (1.25,0)

So, x= -0.25 and 1.25

(ii)

4x^2 -4x-1 =2

here y = 2

The line y= 2 cuts the curve at (-0.5,2) and (1.5,2)

So, x = -0.5 and  1.5

Given equation of the curve is

y= 3x^2-3x -1

(i)

3x^2-3x +2 =2

\Leftrightarrow  3x^2-3x -1 = -1

Here y = -1

The line y = -1  cuts the curve at (0,-1) and (1,-1)

So x = 0 and 1

(ii)

3x^2-3x -1 =x+1

Here y = x+1

The line y -x =1 cuts the curve at (-0.375,0.5) and (1.625,2).

So x = -0.375 and 1.625

Please help I don't understand!

The triangles given below in the diagram are similar by; D: The SSS Similarity theorem.

<h3>How to interpret similar triangles?</h3>

From triangle similarity theorems, we know that;

If a segment is parallel to one side of a triangle and intersects the other two sides, then the triangle formed is similar to the original and the segment that divides the two sides it intersects is proportional.

Now, from the given diagram, we see the ratio of corresponding sides are congruent as;

45/30 = 54/36 = 36/24 = 1.5

Thus, the triangles are similar by SSS similarity theorem
