Answer:
The approximate measure of the largest angle formed by these streets is 
Step-by-step explanation:
we know that
Applying the law of cosines

In this problem we have


----> is the greater side
substitute and solve for angle C


![cos(C)=[152,500-176,400]/150,000](https://tex.z-dn.net/?f=cos%28C%29%3D%5B152%2C500-176%2C400%5D%2F150%2C000)


Step-by-step explanation:
Since this is a rectangle these two equations for the length have to equal each other.
2x+4=7x-1
We now need to get all of the x's on one side and constant numbers on the other side.
add 1 to both sides and subtract 2x from both sides.
5=5x
divide 5 from both sides.
x=1
Answer:
x=20°, and y is 90° btw
Step-by-step explanation:
This is an iscoceles triangle, since the base angles are equal and the altitude bisects one of the angles. 180 - 110 = 70, meaning the angles are 70 , 70 and 2x. We know that 70 + 70 + 2x = 180 from the angle sum theorem, so 140 + 2x = 180, and 40 = 2x. x = 20°
C
Step-by-step explanation:
You do 5 - 2 = 3 and -y = -x so the answer would be C.
