Answer:
graph A
Step-by-step explanation:
The angles are 40 degrees and 140 degrees.
• In plane geometry, a figure which is created by two rays or two lines or line segments that share a common end point is known as angle.
• The two rays which are share a common point are called as sides of the angle an the common end point is called as the vertex.
• Some types of angles are acute angle, right angle, obtuse angle, straight angle and many more.
Let one angle be x
Other angle = 7/2 x
Since it is a linear pair, it’s sum will be 180 degrees.
So, x + 7/2 x = 180
9/2 x = 180
9 x = 360
X = 40
7/ 2 x = 7/2 × 40 = 140
Therefore, the angles are 40 degrees and 140 degrees.

Answer:
angle A is 32.99
Step-by-step explanation:
angle A = ![sin^{-1} (0.544639)](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%20%280.544639%29)
angle A = 32.99
88. James, Priya and Siobhan work in a grocery store.
Here are their Salaries:
=> James makes 7.00 dollars per hour
=> Priya makes 20% more than james
=> Siobhan makes 5% less than Priya.
Let’s solve how much they received per hour.
James = 7 dollars
Priyra
=> 20% more than 7 dollars
=> 7 * .20 = 1.4 dollars
=> 7 dollars + 1.4 dollars = 8.4 dollars
Siobhan = 5% less than 8.4 dollars
=> 8.4 dollars * .05 = .42 dollars
=> 8.4 dollars - .42 dollars = 7.98 dollars.
