Answer:

x + 150 deg = 180deg (being co-interior angles)

:. x = 30 deg

2. y^2 + 7= 32 ( opposite sides of parallelogram are equal)

or, y^2 = 25

or y^2 = 5^2

: . y = 5

3. k= 2y^2 ( opposite sides of parallelogram are equal)

or, k = 2× 5^2

: . k = 50

What is 2/3 x 4 1/5 as a mixed fraction?

EleoNora [17]

=2/3 x 4 1/5
Change 4 1/5 to improper fraction
=2/3 x 21/5

Multiply the two numerators together and multiply the two denominators together

= (2*21)/(3*5)
=42/15

Convert back to mixed fraction

= 2 12/15
Simplify by dividing 3 into top & bottom

ANSWER:
= 2 4/5 simplest mixed fraction

Luis set up an A-frame ladder so that the angle formed between each side of the ladder and the ground is 125 degrees. What is th

Firlakuza [10]

Answer:

70°

found by considering A-frame ladder as a triangle

Step-by-step explanation:

Given that,

angle form on either side of A-frame ladder with the ground = 125°(exterior)

As it is a A-frame ladder so its a triangle, we will find the angle at the top of ladder by using different properties of triangle

1) find interior angle form by A-frame ladder with the ground

125 + x = 180 sum of angles on a straight line

x = 180 - 125

x = 55°

2) find the angle on top of ladder

55 + 55 + y = 180 sum of angle of a triangle

110 + y = 180

y = 180 - 110

y = 70°

Write an equation in point-slope form for the line.<br> (1,3) <br> (0,1)<br> m=4

Anna [14]

Given coordinates (1,3) and (0,1).

In order to find the equation of line, we need to find the slope between given coordinates.

We know slope formula,

m= $\frac{y2-y1}{x2-x1}$

We have (x1,y1) = (1,3) and (x2,y2) = (0,1).

Plugging values of x1,y1,x2 and y2 in slope formula, we get

$m=\frac{1-3}{0-1}$

Simplifying top and bottom of the fraction we got for slope

$m=\frac{-2}{-1}=2$

We got slope m=2.

We are given second point (0,1), where x-coordinate is 0 and y-coordinate is 1.

y-intercept is a point on y-axis, where x=0.

Therefore, y-intercept = 1.

Now, applying slope-intercept form of the linear equation

y=mx+b, where m is the slope and b is y-intercept.

m=2 and b=1.

Plugging values of m and b in slope-intercept form, we get

y=2x+1.

Therefore, point-slope form for the line is y=2x+1.
