Answer:
(11+x)-3
Step-by-step explanation:
11 more than x is another way of saying 11+x
And "less than 3" means subtracting 3 from the terms
So if you put that together it would be
(11+x) -3
Answer:
PQ = 16
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = 
, then
cos60° = 
= 
= 
= ( cross- multiply )
PQ = 8 × 2 = 16
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.
