Answer:
The Area of Δ ABC = 219.13
Step-by-step explanation:
<em>The hard part about this problem is finding the area without the height</em>
The formula to do this is Area = 
A, B, C represent the sides
S represents 
(A + B + C)
In this equation, we will make the base be A, and the other two sides will be B and C
<u>Sides B and C are the same length</u> because they meet at a 90° angle
Lets plug the numbers into the variables
A = 28
B= 21
C= 21
<u>Remember:</u> S represents (A + B + C)
S = (28 + 21 + 21)
S = (70)
S = 35
<em>Lets plug the numbers into the Area Formula now!</em>
Area = 
According to the order of operations, we need to do the calculations in parentheses <u>first</u>
35 - 28 = 7
35 - 21 = 14
35 - 21 = 14
14 x 14 x 7 = 1372
1372 x 35 = 48020
= 219.13
The Area of Δ ABC = 219.13
Here, we are concerned about two variables from the above data set, namely, Condo or co-ops and the Unemployment rate. We use the CORREL function of Excel to calculate the correlation coefficient rate and it is = R = -0.01873.
A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.
The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.
The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.
Correlation values above 0. eight are deemed to signify a strong tremendous linear courting between the variables. Values among zero and 0. three imply a vulnerable relationship or none.

Hi there!
Here is the step by step solving :
-19 = 5(x + 9)
Distribute the 5 to the entire parentheses
5 × x = 5x
5 × 9 = 45
-19 = 5x + 45
Subtract 45 from each side of the equation
-64 = 5x
Divide each side of the equation by 5
-64/5 = x
So your answer is : A. x = -64/5
There you go! I really hope this helped, if there's aything just let me know! :)
Answer:
Step-by-step explanation:
take 45 degree as reference angle
using sin rule
sin 45=opposite/hypotenuse
1
=x/16
x=16/
x=8
