Answer:

m∠X = 29°

m∠V = 61°

m∠W == 90°⇒given

Step-by-step explanation:

∵ ΔXWV is right angle at W

∴ m∠W = 90°

∴ m∠X + m∠V = 180° - 90° = 90°

∵ m∠X = 2x + 5 and m∠V = 4x +13

∴ 2x + 5 +4x + 13 = 90

∴ 6x + 18 = 90

∴ 6x = 90 - 18 =72

∴ x = 72/6 = 12

∴ m∠X = 2(12) + 5 = 29°

∴ m∠V = 4(12) + 13 = 61°

On paper, make a rectangle that has points A and B as two of its vertices and has a perimeter of 40 units. Draw and label the tw

Westkost [7]

Answer:

$A(x,y),B(x+10,y),C(x+10,y-10) \:and\: D(x,y-10)$

Step-by-step explanation:

If a Rectangle has a perimeter of 40 units, then we can write that formula and find the a formula for the coordinates:

$\left\{\begin{matrix}w+l=20 & \\ w*l=100 & \end{matrix}\right.\Rightarrow w=20-l\Rightarrow (20-l)l=100\Rightarrow -l^2+20l-100=0\Rightarrow l^2-20l+100\Rightarrow (l-10)(l-10)\Rightarrow l=10\therefore l=10\: and\: w=10$

Therefore we can say:

$A(x,y),B(x+10,y),C(x+10,y-10) \:and\: D(x,y-10)$

Technically when $w=l$ in this rectangle is a square, a degenerate square.

Write a division number story with an answer of 3/5

katrin [286]

Peter has 4 friends. He invited them to his home. He ordered a pizza of his favorite and made it into 5 slices.

Few minutes later, one of his friends Smith came and they enjoyed one slice of pizza each.

Now, the question is what portion of the pizza left for his remaining friends?

Answer :

Peter made the pizza into 5 pieces.

So, $1=\frac{5}{5}$

Peter and Smith had $\frac{1}{5}$ th of the pizza each.

So, the remaining portion = $\frac{5}{5} -(\frac{1}{5}+\frac{1}{5})$

$=\frac{5}{5} -\frac{2}{5}$

$=\frac{3}{5}$
