Answer:

The answer to your question is ∠3 = 24°

Step-by-step explanation:

Data

∠4 = 11x

∠3 = 4x

Process

1.- From the picture, we know that angles 3 and 4 are complementary so if we sum them up the result is 90°.

∠3 + ∠4 = 90°

2.- Substitution

4x + 11x = 90°

3.- Simplification and result

15x = 90°

x = 90/15

x = 6

4.- Find angle 3

∠3 = 4(6)

∠3 = 24°

A square has an area of 100 in ^2. What is the perimeter of the square

almond37 [142]

Area of a square is its side length squared...

A=s^2 solving for s...

s=√A

The perimeter of a square is 4 times its side length...

P=4s, and since s=√A

P=4√A, and we are told that A=100 in^2 so

P=4√100

P=4*10

P=40 in

Convert to the product of multiplication a^2-b^2-4b-4

kirill [66]

$a^2-b^2-4b-4$ in form of multiplication is $(a-b)(a+b)-4(b+1)$ .

Step-by-step explanation:

We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .

Here , we need to convert to the product of multiplication

a^2-b^2-4b-4 or , $a^2-b^2-4b-4$ :

⇒ $a^2-b^2-4b-4$

We know by identity that , $p^2-q^2 = (p-q)(p+q)$

⇒ $(a-b)(a+b)-4b-4$

Taking common term out as -4 :

⇒ $(a-b)(a+b)-4(b+1)$

Therefore , $a^2-b^2-4b-4$ in form of multiplication is $(a-b)(a+b)-4(b+1)$ .
