Answer:
Therefore,
Step-by-step explanation:
Given:
Consider In Right Angle Triangle ABC
∠B = 90°
∠C = ∠A = 45°
AB = y
BC = x = adjacent side
AC = 8 = hypotenuse
To Find:
x = ?
y = ?
Solution:
In Right Angle Triangle ABC by Cosine Identity we have
substituting the above given values we get
As The triangle is 45 - 45 - 90
It is an Isosceles Right triangle
..... Isosceles Triangle property
Therefore,
A to line b
b to line c
c to line d
d to line e
e to line a

Answer: Use order of operations (PEMDAS). Answer is 45.72.
Step-by-step explanation:
First, solve inside parenthesis:
(5.25*1 1/5 - 4.5*4/5)
Convert 1 1/5 into decimal. It will be easier. 1 1/5 is the same as 1.2
Do multiplication and division first.
5.25*1.2 = 6.3
Now it looks like: (6.3 - 4.5*4/5)
Convert 4/5 to a decimal: 4/5 = 0.8
(6.3 - 4.5*0.8)
Multiply 4.5*0.8 = 3.7
Subtract (6.3 - 3.7) = 2.6
Now the full equation is: 19.6*2 1/5 + (2.6)
2 1/5 as a decimal: 2.2
Multiply 19.6*2.2 = 43.12
Now the equation is: 43.12 + 2.6
Add 43.12 + 2.6 = 45.72
Answer:
<h2>There are 33 pennies, 66 dimes and 66 nickels</h2>
Step-by-step explanation:
let the pennies be p
nickles be n
and dimes be d
p+n+d=165----------------1
Also n=2p
d=2p
substitute n=2p and d=2p in the eqn 1
p+2p+2p=165
5p=165
p=165/5
p=33
n=2(33)
n=66 nickels
d=(33)
d=66dimes
