Given:
m∠2 is 19° more than m∠1.
To find:
The value of m∠1.
Solution:
Let the measure of ∠1 be x.
Then, 
, it means the sum of m∠1 and m∠2 is 109°.
Divide both sides by 2.
Therefore, the value of m∠1 is 45°.
Answer:
137/1000
Step-by-step explanation:
I see you want to solve -2x + y + 6 = 0 2x + y - 8 = 0 simultaneously. Next time, please put each equation on its own line, like this:
-2x + y + 6 = 0
2x + y - 8 = 0
or separate the two equations with "and" or some other symbol.
We can easily eliminate x by adding these 2 equations together:
-2x + y + 6 = 0
2x + y - 8 = 0
-------------------
2y - 2 = 0, which yields y = 1. This is the equation called for in this problem. You were not asked to find x.
We already know that the area of the rectangle increased by a square of the factor 7. So the dilated area of it (which we will call "Ad"), is:
Ad= (47)(7^2)
Ad= 47x49
Ad= 2303 m^2
What is the area of the dilated rectangle? The area of the dilated rectangle is 2303 m^2.
Hi there!
f(x) = 7x - 4
Rewrite f(x) with y:
y = 7x - 4
Swap the x and y variables:
x = 7y - 4
Solve for y:
x + 4 = 7y
y = (x + 4)/7
