Answer:
Step-by-step explanation:
The given figure above is an inscribed quadrilateral with all four vertices lying on the given circle, thereby forming chords each.
Therefore, the opposite angles of the above quadrilateral are supplementary.
This means:
, and
Find the measure of d:
Subtract 57 from both sides.

Answer:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that 
A slope parallel to it will have the same slope. So it will be 1/4.
A perpendicular slope will have the opposite reciprocal of the given slope. So it will be -4.
Answer:
Step-by-step explanation:
Known facts
- Marisol burned 670 calories
- Ling burned x fewer calories than Marisol
Setting up the equation
# of calories that Ling burned = Marisol's calorie - x = 670 -x
