Answer:
f=regrfdfdgfgsghgs
Step-by-step explanation:
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
It should evaluate the middle term -2*6/2 first.
Answer:
20%
Step-by-step explanation:
890+400+650+420+590= 2950
590/2950= 20%
The surface area of a rectangular prism is given by
... S = 2(LW +H(L+W))
For your dimensions, the surface area is
... S = 2(3·1 + 2(3+1)) = 2(3 + 8) = 22 . . . ft²
