Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = 
, then
sin60° = 
= 
= ( cross- multiply )
x 
= 28 ( divide both sides by )
x = 28
-----------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° = , then
tan60° = 
= 
= ( multiply both sides by y )
14 = y ( divide both sides by )
y = 14

depends on how you understand math.
Answer:
a=2/3
Step-by-step explanation:
3(4a+1)+3a=13
12a+3+3a=13
15a+3=13
15a=10
a=2/3
Answer:
-7 7/15
Step-by-step explanation:
-11 2/3 -(-4 1/5) = -11 2/3 + 4 1/5. Now, we need to find the LCM of 3 and 5. The LCM of 3 and 5 is 15 because 15 is the lowest number that can divide both 3 and 5 separately and both results will still be whole numbers.
Now, we have -11 10/15 + 4 3/15.
-11 10/15 + 4 3/15 = -7 7/15.
Well in order to do that you need to do -4 2/3 - -7 1/5.
