Answer:
A line is an infinite two dimensional figure
Step One
Find RST
The two base angles are given as equal and one of the is 28. So is the other one.
SRT = 28
STR = 28
All triangles have interior angles that add up to 180 degrees.
RST + SRT + STR = 180
28 + 28 + RST = 180
56 + RST = 180 Subtract 56 from both sides.
RST = 180 - 56
RST = 124
Step two
Find the exterior angle
The exterior angle = Sum of the two remote interior angles (RST + SRT)
The exterior angle = 28 + 124
The exterior angle = 152
Step Three
Find the value of x
2*x = 152 Divide by 2
x = 152 / 2
x = 76
There is a quicker way of finding the exterior angle. I didn't see it until I had written step two.
The exterior angle + STR = 180 degrees. They are supplementary.
The exterior angle + 28 = 180
The exterior angle = 180 - 28
The exterior angle = 152
Answer:
Just start with 14 and go up and then start at 150 and go down by 12 until they meet
Answer:
6.28
Step-by-step explanation:
This problem bother on the mensuration of flat shapes, a circle.
Volume v =
Diameter d= 
Radius r = 
Since we are required to solve for the circumference of a circle
The expression for the circumference of a circle is given as
The question insist that we type just a number hence the circumference
of the plug is 6.28
You have to perform operations inside parenthesis first:
And finally,
