It is extremely important to understand the words of the given problem. There are numerous information's of immense importance that are already given in the question. Based on those information's the answer to the question can be easily deduced.
Let us assume the unknown number = x
Then
14x - 34 = 78
14x = 78 + 34
14x = 112
x = 112/14
= 8
So the unknown number in the given question is 8. I hope the procedure is clear to you and you got the answer that you wanted.
Cause their sum is 90 degree and I think the name for them is d, supplementary
Answer:B hope this helps! :D
Step-by-step explanation:
Answer:
y = 2 units
Step-by-step explanation:
We can solve this in 2 ways, both ways would give the same answer:
<u>#1) Sin(45) = </u>
<u />
=> Sin(45) * y = 
=> y = 
=> y = 2
<u>#2) Cos(45) = </u><u />
=> Cos(45) * y =
=> y = 
=> y = 2
Hope this helps!
