I'm not completely sure about this answer since it's been 2 months since I've done geometry but to find the measure of <ADC, it's half of the arc measure of arc AE. (48+68)/2=58 so the measure of <ADC is 58 degrees.
The measure of arc AE is 68 because it is the measure of <ABE doubled.
The answer is 3 (x+b) (x-2)
Yw! :)
The equation of the vertical line is 
Explanation:
It is given that the vertical line passes through the points 
For vertical line, the slope is undefined.
Hence, 
Let us substitute the coordinate
in the equation
, we have,

Simplifying, we have,


where
and 
Substituting the values of a, b and c in the equation
, we have,

Thus, the equation of the vertical line is 
Answer:
b
Step-by-step explanation:
Answer:
The surface area of the model is 
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of four lateral triangles
so
