For a square and rectangle it is Area=length*width
(9+8+2)/(4+9+8+2)=19/23=82%
Therefore very likely
Answer:
A)5
Step-by-step explanation:
I answered the question already.
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
