Answer:
C = 57.2
Angle S corresponds to angle C
Both triangles are symmetrical to each other.
For this case we must find the solution of the following expression:

If we isolate a term and we equate to zero, we have:

Subtracting 7 on both sides of the equation we have:

Thus, the solution of the expression is given by:

ANswer:

The equation that you must use is y=15x+15
so x would be 1,2,3,4,5 and y would be 30,45,60,75,90
X/3 > 7 <== ur equation
multiply both sides by 3
x > 7 * 3
x > 21 <== ur solution
Answer: 27.47
Step-by-step explanation:
(sin(70) * 10) / sin(20)) = 27.47
don't know much, but try that
