Sin74 = Cos16
cause 16 + 74 = 90
Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :
Sin(30) = Cos(60)
and also
Tan(30) = Cot(60)
Answer:
Since the triangles are congruent, AB=ED so AB=14
Angles F is congruent to angle C so F=39 degrees
Step-by-step explanation:
Answer:
13 ft.
Step-by-step explanation:
Lateral Surface area of a cube is the area of 4 sides, front side, back side, left side face and right side face.
It can be seen seen from the attached figure as well.
Each face in a cube is a square. And each side in the cube is equal.
So, Lateral surface area is nothing but 4
area of a square.
And we know that area of a square =
.
Hence, Lateral surface area = 
As per question:
= 676

Hence, side length of cube = 13 feet.
Answer:
The final price is $66.
Step-by-step explanation:
This question can be solved by a rule of three.
The initial price was of $120.
Initially, there was a discount of 15%. Then, there is another discount on the initial price. So the total discount is of 15+30 = 45%.
So the final price will be 100-45 = 55% = 0.55 of the initial price.
So
$120 - 1
x - 0.55

The final price is $66.
Answer:
Step-by-step explanation:
What you are asking is to fill in the blank in the following sentence.
_______ % off this imported futon.
Solution
500 x/100 = 425 Divide the left by 100
5x = 425 Divide both sides by 5
5x/5 = 425/5 Simplify
x = 85
That is not the answer. That is the % paid.
The reduction is 100% - 85% = 15%
So your blank would contain 15%
Check
15% of 500 = 15/100 * 500 = 75 which is what they the store is offering you off.
