Answer:

width = 6

length = 4

Step-by-step explanation:

perimeter = 2L + 2W

L = W - 2

plug in perimeter:

20 = 2L + 2W

you know the length is 2 less than the width

plug in (w - 2) for L:

20 = 2(w - 2) + 2w

solve for w:

20 = 2w - 4 + 2w

20 = 4w - 4

4w = 24

w = 6

now plug in 6 for w in either equation, whichever is easier to solve:

L = 6 - 2

L = 4

width = 6

length = 4

Answer:

1. 2x + 30° = 180°

2x = 150°

x = 75°

2. (2x - 24)° + (x + 12)° + (x - 8)° = 180°

4x - 20 = 180°

4x = 200

x = 50°

$\large \mathfrak{Solution : }$

As we know :

Dividend = Divisor × Quotient ( taking remainder as 0 )

So, Quotient = Dividend ÷ Divisor

by using the above relation we can say :

q = t ÷ 23

therefore, correct option is C. t ÷ 23
