Describe a scenario where the pythagorean theorem could be used in real life
masya89 [10]

Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope. You can use this information to cut properly sized beams to support the roof, or calculate the area of the roof that you would need to shingle.

PLEASE<br> What is the solution to the equation 4 ( b − 2 ) − 10 = 2b + 6 ?
maxonik [38]
Answer: 12

Step by step explanation:
First simplify both sides of the equation
( 4 )( b ) + ( 4 ) ( - 2 ) + -10 = 2b + 6 (distribute)
4b + -8 + -10 = 2b + 6
(4b) + (-8 + -10 ) = 2b + 6 (combine like terms)
4b + -18 = 2b + 6
4b - 18 = 2b + 6
Then subtract 2b from both sides
4b - 18 - 2b = 2b + 6 - 2b
2b - 18 = 6
After that you add 18 to both sides
2b - 18 + 18 = 6 + 18
2b = 24
2b/2 = 24/2
b = 12

If AABC= A DEF, which congruences are true by CPCTC? Check all that
jolli1 [7]

Answer:

Options A, B and D

Step-by-step explanation:

If the two triangles are congruent, their corresponding parts will be congruent.

If ΔABC ≅ ΔDEF

By the property of CPCTC,

AB ≅ DE

AC ≅ DF

BC ≅ EF

∠A ≅ ∠D

∠C ≅ ∠F

∠B ≅ ∠E

Therefore, Options A, B and D are the correct options.
