Write An Equation To Find The Value Of X So That Each Pair Of Polygons Has The Same Perimeter. Then Solve

Answers

Answer 1

The Pythagoras Theorem:

the base squared and height squared added is equal to the hypotenuse squared.

so

(x+6)² + (x+3)²= (x+9)²

x²+36+12x+x²+9+6x = (x+9)²

2x²+45+18x=x²+81+18x

x²=36

x=√36

X= 6

now

(x+6)= 12

(x+3)=9

(x+9)=15

haha sorry correct it pls

The area of the lateral surface of the cube is 12.96 cm²

Step-by-step explanation:

The lateral surface area

4 × (1.8 cm)²

An objects lateral surface are the surfaces of the object that exclude the top and bottom surfaces

In a cube, the lateral surface are the vertically oriented (with respect to the base and the top which are then oriented horizontally) surfaces of the cube

Therefore, the lateral surface area of the cube consist of four vertically oriented equal sized faces, each with side 1.8 cm

The area of the lateral surface of the cube = The area of the four vertically oriented faces of the cube

∴ The area of the lateral surface of the cube = 4 × 1.8 cm × 1.8 cm = 12.96 cm.²

A family went to a restaurant for dinner. The subtotal for the meal including tax is $65.90. The family decided to leave a 20% tip. How much did the family pay total including tip?

120

Answers

Answer would be 110 because if a figure has 4 angles all it's angle lengths add up to 360°, so since one of the angles is 70° and there is another angle that's identical to it, 70+70= 140, so you have to do 360-140 which gives you 220, and 220/2 = 110°

Answer:

110

Step-by-step explanation:

as a trapezoid contains of angles that add up to 360 .....and the top angles are equal and the bottom angles are equal ...therefore >v equals to 70 and w as well and x are equal to 110 each
