Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° = 
, cos30° = 
, then
sin30°= 
= 
= ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° = 
= 
= ( cross- multiply )
2y = 10 ( divide both sides by 2 )
y = 5
"quotient of" means divide or fraction bar ... you should look for the word "and" to determine where to place your division sign or fraction bar
ANSWER:
or
(2x - 1) ÷ (3x + 5) ←Used parenthesis because they quantity 2x - 1 is separated from the quantity 3x + 5 by the word "and"
The correct answer to this is:
ROTATIONS AND TRANSLATIONS
Reflection and rotation can also be used but since their both grouped with dilations, they can't be used. When dilation is used, the size of the shape is changed and congruence won't be possible anymore . That's why the answer is the first option.
