Answer:

x = 6 degrees

Step-by-step explanation:

A straight line is 180 degrees and we can make out three angles the form it, this means the three of them add to 180 using the straight angle theorem:

5x + x + 54 + 90 = 180

6x + 144 = 180

6x = 36

x = 6

Answer:

Simplifying

5x + x = 54

Combine like terms: 5x + x = 6x

6x = 54

Solving

6x = 54

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '6'.

x = 9

Simplifying

x = 9

Answer:

$\sf \dfrac{3}{4y}$

Step-by-step explanation:

Simplify:

45 = 5 * 3 * 3

60 = 5 * 3 * 2 * 2

GCF = 5*3 = 15

$\sf \dfrac{45x^2}{60x^2y}=\dfrac{45}{60y}$

$\sf =\dfrac{45 \div 15}{60y \div 15}\\\\= \dfrac{3}{4y}$
