Answer:
8
Step-by-step explanation:
p = ?
h = 10
b = 6
Now,
p2 = h2 - b2
p2 = ( 10)2 - (6)2
p2 = 100 - 36
p2 = 64
p = root under (64)
p = 8
1) Painting on a Wall:<span> Painters use ladders to paint on high buildings and often use the help of Pythagoras' theorem to complete their work. The painter needs to determine how tall a ladder needs to be in order to safely place the base away from the wall so it won't tip over. In this case the ladder itself will be the hypotenuse. Take for example a painter who has to paint a wall which is about 3 m high. The painter has to put the base of the ladder 2 m away from the wall to ensure it won't tip. What will be the length of the ladder required by the painter to complete his work?
2) you need to come up with a drawing for it.
3)</span>You can calculate it using Pythagoras' theorem:
(5)<span>2 </span>+ (2)2 =
25 + 4 = C2
√100 = C
5.3 m. = C
Thus, the painter will need a ladder about 5 meters high.
hope this helps you
X^2+x=2
first set to zero
x^2+x=2
subtract 2 from both sides
x^2+x-2=0
factor because if you have
x times y=0 then assume x and/or y=0 so
factor x^2+1x-2
to factor you find what 2 number add to 1 and multiply to get -2
the numbers are -1 and 2 so
it factors out to
(x-1)(x+2)=0
assume each is zero
x-1=0
add 1 to both sides
x=1
x+2=0
subtract 2 from both sides
x=-2
x=1 or -2
