2a+4b=324
Solve for a and b. a is the # of borogoves, b is the # of mome raths.
All positive integers less than or equal to 72<span />
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° =
, cos45° =
, thus
sin60° =
=
=
( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp = 
Now consider the right triangle on the right, using the cosine ratio
cos45° =
=
=
( cross- multiply )
x =
×
=
→ C
Answer:
Step-by-step explanation:
common denominator is 20
20+4+10 is 34
34/20 is 1 14/20 or 1 7/10
