1. Use precise mathematical language to justify and explain each mathematical process. A ladder is placed against a wall to reach the highest window of a house. A right angle is formed
by the wall of the house and the ground.
1. Sketch a diagram to represent the situation.
2. If the ladder is 20 feet long and the window is 12 feet high, how far is the base of the ladder
from the wall?
3. Could a 15 foot ladder be placed at the same 12 feet high window, but 10 feet from the house?
Justify your answer.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the weight of the object inside the box!

answer

a. √7.√5

b. 42. -√2

d. √3.√2

step by step explanation

when you multiply a irrational and any number, we get the result as irrational number.

√2 = irrational number

√3 = irrational number

√5 = irrational number

√16 = 4

therefore, the following are the irrational number

a. √7 . √5 = irrational number

b. 42.-√2 = irrational number

d. √3.√2 = irrational number

you.
