Answer:
It's the last choice:
2x + y - 1 = 0.
Step-by-step explanation:
x - 2y - 3 = 0
Convert to slope-intercept form in order to find the slope:
-2y = -x + 3
y = 1/2x - 3/2
So the slope is 1/2. The slope of a line perpendicular to this is -1 / 1/2 = -2.
Using the point-slope form to find the required equation:
y - y1 = m(x - x1)
x = 4 and y = -7 so we have:
y + 7 = -2(x - 4)
y + 7 = -2x + 8
2x + y - 1 = 0 is the answer.
Ans: The measure of exterior angle i.e angle A is -52⁰.
You meant to say that the measure of an angle A is on exterior angle so let me elaborate it you clearly,
Hello!
You first have to find the total amount of apartments
35 + 55 = 90
There are 90 apartments
Then you find the percentage of them have a balcony
You do this by taking the amount of apartments that have a balcony over the total amount of apartments
35/90 = 0.39
0.39 as a percent is 39%
The answer is 39/100 or 39%
Hope this helps!
