Answer:
Step-by-step explanation:
Given: Perimeter of triangle= 72 units
Measure of one of the side= x units
Measure of second side = 3x units
We know the perimeter of triangle is equal to sum of all sides.
Now, finding the possible value of x
forming an inequality to determine the value of x
Remember triangle has three sides, however, measure of only two sides are given.
⇒ 
⇒ 
Dividing both side by 4
⇒ 
∴ The inequality to represents all possible values of x is
Find the separate areas.
We have a triangle with base 5 cm and height 5 cm, calculate the area:
Plug in what we know:
Multiply:
Now for the two quarter circles, we know that if we put these two together we will end up with a semi-circle with radius 5 cm. The formula for the area of a circle is:
A semi-circle is half of a whole circle, so the formula for the area of it must be:
Now plug in what we know(use 3.14 to approximate for pi):
Simplify the exponent:
Multiply:
Now add this to the area of the triangle to find the approximate area of the entire figure(round to the nearest tenth):
Answer:
T' 
Step-by-step explanation:
See the diagram attached.
This is a unit circle having a radius (r) = 1 unit.
So, the length of the circumference of the circle will be 2πr = 2π units.
Now, the point on the circle at a distance of x along the arc from P is T
.
Therefore, the point on the circle at a distance of 2π - x along the arc from P will be T' , where, T' is the image of point T, when reflected over the x-axis. (Answer)
