Answer:
A= 75.06 Sq Cm
Step-by-step explanation:
Please refer to the picture attached with this.
In ΔABD
AB = 8.5 , AD = 6 and say BD = x
Applying Pythagoras theorem in this triangle
Pythagoras theorem says

where c is the side opposite to the right angle, and b and a are the other two sides of the right angled triangle.




Hence side 
a = 6.02+19
a = 25.02
Now we apply the formula for area of a triangle which is given as

Where b is the base , here we have base as a = 25.02
h is the height , here h = 6
Putting these values in Formula we get



Hence Area of the triangle is 75.06 sq cm
Answer: The slope is 0
Step-by-step explanation:
The slope is the difference between the y coordinates divided by the difference between the x coordinates.
Y: 9 - 9 = 0
x: -7-2 = -9
0/-9= 0
The answer for your question is 686
x=96
all interior angles equal 180
Subtract exterior andgles by 180 to get interior angles because they are supplementary
180-134=46
180-130=50
Get the third angle inside the triangle
180-50-46=84
subtract by 180 to get x because they are supplementary
180-84=96
Therefore x =96
