Answer:
x=70
Step-by-step explanation:
The same side interior angles add to 180 degrees when m and n are parallel
45+ 2x-5 = 180
Combine like terms
40+2x = 180
Subtract 40 from each side
40-40+2x= 180-40
2x= 140
2x/2 =140/2
x =70
Stem-and-Leaf-plot represents data by separating each value into two parts. Dot plot uses a graph in which each data value is plotted as a point along a horizontal scale of values. The difference is Dot Plots use graphs to organize data and Stem-and-Leaf plot separates the data into two parts
The answer is D. 60'. You add both angles together, then subtract them from 180.
60+70=120
180-120=60
Answer:
C. 40
Step-by-step explanation:
the fraction 20/6 in a calculator makes 3.333 repeating and 40/12 does the same.
Answer:
≈13degrees
Step-by-step explanation:
It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,
Using the formula, 
where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get
⇒
Therefore, 
⇒
⇒
Thus, the latitude of B is=12.53 degrees≈13degrees
