Find the four angles A, B, C and D of the parallelogram ABCD.<br>А<br>3x<br>2x<br>5x​
Greeley [361]

Ans: We can use Angle sum property:

A + B + C + D = 360

A + 3x + 2x + 5x = 360

A + 10x = 360

A = 360/10x= 36x

A = 36x

Taya2010 [7]

Answer:

Step-by-step explanation:

12

This is what we call a 45-45 traingle

This means that the lengths of the two non-hyptonouse lengths are the same

luckily we're given that it's 6√2

We can then use the pathagaryem theory to solve for the last side

we have

(6√2)²+(6√2)²=x²

Put this into your calculator and get

144= x²

x = 12

What is the initial value for the function f(x)=3(5/4)x
In-s [12.5K]
For
f(x)=3\left(\dfrac{5}{4}\right)^{x}
you seem to want to know the value of f(0). Put 0 where x is, then evaluate.
f(0)=3\left(\dfrac{5}{4}\right)^{0}=3\cdot 1=3

The initial value of the function is 3.

_____
You will observe that when x=0, the exponential term evaluates to 1. This is true regardless of its base. Thus f(0) is always the coefficient of the exponential term—in this case, 3.
