Sorry guys today is not my day : (

First question...

F = Floor = 3

W = Wall = ?

H = Hypotenuse = 10



3² + W² = 10²

W² = 10² - 3²

W² = 91

W = √91

Answer (3) : √(91) feet [Rounded: 9.54 feet]



Last question...

L² = 112

L = √(112) = √(28)√(4) = √(7)√(4)√(4) = 4√(7)

Answer (4):

4√7 feet

3.
pythagroen theorem
for a right triangl of legs legnth a and b and hypotnuse c
a^2+b^2=c^2
legs are 3 and height
hypotnuse=legnth of lader=10

h^2+3^2=1^2
h^2+9=100
minus 9 both sides
h^2=91
sqr both sides
h=9.539
h=9.54 ft

4.
area=side^2 for  a square
112=side^2
sqrt both sides
√112=side
(√16)(√7)=side
4√7 ft=side

3. 9.54 ft
4. 4√7ft

Ithink the answer is b

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
