Answer:
X = 18
Y = 9√3
Step-by-step explanation:
use sin equation for right angle triangle
The sine of the angle
= ( the length of the opposite side ÷ the length of the hypotenuse.)
according to this question,
sin 30 = 9 / X
1/2 = 9 / X
X = 18
use cosine to find y
The cosine of the angle
= (the length of the adjacent side ÷ the length of the hypotenuse.)
cos 30 = y/x
√3/2 = y/ 18
y = 9 ✓3

Answer:
Addition Property of Equality
Step-by-step explanation:
That property says it's OK to add the same number to both sides of an equation
If a = b, then a + c = b + c
Answer:
X = 2
Y=7
Step-by-step explanation:
The explanation is in the pictures
It's letter c
multiply the coefficient then just add the degrees of each letter
