Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Hypotenuse² = Base² + Length²
The height of the building is 32.8 feet
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
If you place a 26-foot ladder against the top of a building and the bottom of the ladder is 20 feet from the bottom of the building.
This can be written as,
Hypotenuse = 26 feet
Base = 20 feet
Height = height of the building
Now,
Applying the Pythagorean theorem.
Hypotenuse² = Base² + Length²
26² = 20² + Height²
Height² = 676 + 400
Height² = 1076
Height = √1076
Height = 32.8 feet
Thus,
The height of the building is 32.8 feet

i cant solve this help –8x + 15 < 71
Answer:
x > -7
Step-by-step explanation:
Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction
First, subtract 15 from both sides:
-8x + 15 (-15) < 71 (-15)
-8x < 71 - 15
-8x < 56
Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:
(-8x)/-8 < (56)/-8
x < (56)/-8
x > -7
x > -7 is your answer.
~
Answer:
Any number greater than but excluding -7.
Step-by-step explanation:
-8x + 15 < 71
-8x < 71 - 15
-8x < 56
56 divided by -8 = -7
So, that means anything greater than -7 would result in a lower number than 71.

A rectangle and a triangle have the same area.
The dimensions of the rectangle are 3 cm and 10 cm. The base of the triangle is 6 cm.
What is the height of the triangle? How do you know?
Answer:
Height of the triangle = 10 cm
Step-by-step explanation:
Given:
Dimensions of rectangle = 3 cm , 10 cm
Base of triangle = 6 cm
Find:
Height of the triangle
Computation:
Given that area of rectangle is equal to area of triangle
So,
(l x b) = (1/2)(b)(h)
(3 x 10) = (1/2)(6)(h)
30 = 3(h)
h = 10
Height of the triangle = 10 cm

All Choose... are Choose... , but only Choose... with 4 equal sides are Choose...
Answer:
D. Neither Ryan nor Addy
Step-by-step explanation:
Square:
A square is a quadrilateral that has equal sides and all angles equal to 90 degrees.
Rectangle:
A rectangles is a quadrilateral that has equal or unequal sides and all angles equal to 90 degrees. All rectangles are not squares.
Rhombus:
A rhombus is a quadrilateral that has equal sides and all angles may or may not be equal to 90 degrees. All squares are rhombus. But all rhombus are not squares.
As both Ryan and Addy have missed out one property of square therefore both of them are incorrect.

if 10 pgs = 120 mins
then 15 pgs = 15 × 120÷10
=1800÷10

Kelly and Brandon have a combined age of 32.
They have an age difference of 6 (Kelly is older).
Write a system of equations to find out how old Kelly is
and how old Brandon is.
Answer:
Kelly is 19; Brandon is 13
Step-by-step explanation:
k + b = 32. Also: k = b + 6.
Substituting b + 6 for k in the first equation, we get b + 6 + b = 32, or
2b = 26. Then b must be 13, and k must be 13 + 6, or 19.
Kelly is 19; Brandon is 13.
Answer:
Brandon is 13, Kelly is 19.
Step-by-step explanation:
Let's set up our equations.
Kelly and Brandon have a combined age of 32.
K + B = 32
They have an age difference of 6. Kelly is older.
K - B = 6
Let's shift the equation around a little.
K - B = 6
Add B to both sides.
K = B + 6
Now let's plug K into our first equation.
K + B = 32
(B + 6) + B = 32
Combine like terms.
2B + 6 = 32
2B = 26
Divide both sides by 2.
B = 13
Now that we know Brandon is 13, we can find Kelly's age.
K + B = 32
K + 13 = 32
K = 19
Kelly is 19.
