The longer leg is the leg adjacent to the larger angle
so 60
length of longer leg = 4 sin60 = 2sqrt(3)
Answer:
see explanation
Step-by-step explanation:
the sequence is linear, that is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₈ = 18 and a₁₂ = 26 , then
a₁ + 7d = 18 → (1)
a₁ + 11d = 26 → (2)
subtract (1) from (2) term by term to eliminate a₁
4d = 8 ( divide both sides by 4 )
d = 2
substitute d = 2 into (1) and solve for a₁
a₁ + 7(2) = 18
a₁ + 14 = 18 ( subtract 14 from both sides )
a₁ = 4
then
a₂₀ = 4 + (19 × 2) = 4 + 38 = 42
Width = 4x
You haven’t provided enough data, but lets say length (x) = 5
Then do the following:
Width = 4x
= 4 x 5
= 20
Answer:
Yes
Step-by-step explanation:
X=-5-3y
If we take X to the other side and -5 to the other side then it becomes
3y=-5-X
So both the equations are same
so they have the same answer
Answer: -45
Step-by-step explanation: According the order of operations, or PEMDAS, we first simplify what's inside the parentheses.
So here, we have 7 + -12 which is -5.
When we are adding a negative, think of it as subtracting a positive so 7 + -12 can be changed to 7 - 12 or -5.
Now, we have (-5) (9).
Since a negative multiplied by a positive gives us a negative, -5 multiplied by 9 will give us an answer of -45.
Therefore, (7 + 12) × 9 = -45.
