What your going to do is a keep change flip so you keep 1/2, change the division sign to a multiplication sign and flip the 14/5 into 5/14 after that you multiply straight across

Step-by-step explanation:

<u>Angles and Lines</u>

We must recall:

The sum of the internal angles of a triangle is 180°
Two linear angles add up to 180°

The image shows a triangle and the extension of its base to form two linear angles.

Note from the triangle, angle R is what it takes to get to 180°:

$m\angle R=180-25x-(57+x)$

From the line SQ, angle R what it takes to get to 180°. Thus:

$m\angle R=180-45x$

Equating:

$180-25x-(57+x)=180-45x$

Subtracting 180 and simplifying:

$-25x-57-x=-45x$

$19x=57$

Dividing by 19:

x=3

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar.

Answer: C= (3,2) and D=(2.2, 2.8)

Step-by-step explanation:

The coordinates of point P(x,y) divides a line segment having end points M ${x_1,y_1}$ and N $(x_2,y_2)$ in m:n will be :-

$x=\dfrac{mx_2+nx_1}{m+n}\ ;\ y=\dfrac{my_2+ny_1}{m+n}$

Given : The endpoints of AB are A(1,4) and B(6,-1).

If point C divides AB in the ratio 2 : 3, the coordinates of point C will be :-

$x=\dfrac{2(6)+3(1)}{2+3}\ ;\ y=\dfrac{2(-1)+3(4)}{2+3}$

Simplify,

$\\\\\Rightarrow x=3\ y=2$

Thus , coordinate of C= (3,2)

If point D divides AC in the ratio 3 : 2, the coordinates of point D will be :-

$x=\dfrac{3(3)+2(1)}{3+2}\ ;\ y=\dfrac{3(2)+2(4)}{3+2}$

Simplify,

$\\\\\Rightarrow x=3\ y=2$

Thus , coordinate of D= (2.2,2.8)

Find the solution set to this inequality:

Goryan [66]

Answer:

Step-by-step explanation:

2x-3 > 2x-5/2

⇒2x-3/1=2x-5/2

⇒(2x-3)×2=(2x-5)×1

4x-6=2x-5

⇒2x-1>0

⇒2x>1

⇒x>1/2

What would be the correct similarity statement for these triangles?

aalyn [17]

Answer:

A) FGE~HGE

Step-by-step explanation:

Because all of the points match up with the points on the other side.

It would be similar to closing a sand-witch and lining up all the edges with each other.
