Answer:
- For semicircle examples, skip to section 1
- For parallelogram examples, skip to section 2
To find the perimeter of a parallelogram, use the formula, 2(a+b)
To find a semicircle perimeter, use the formula of (π × r) + (2 × r)
<em>note that without any specified values for the shapes, you cannot properly find a value.</em>
__________
1.
So let's say I have a bowl that is ironically shaped like a semicircle, and its radius is 6 units.
- What we know is that the semicircle has a radius of 8 units, and what we must find is the perimeter.
Use the formula from earlier.(Using 3.14 for pi)
__________
2.
And let's say I have a new origami shape that contains a figure similar to a parallelogram. We want to find it's perimeter. What is the first step?
- The first step is using the parallelogram perimeter formula as listed below and above.
Where <em>a</em> is the side and <em>b</em> is the base.
- And let's also say this figure has a base of 7 and a side of... let's say a side length of 9
- Now that we have values, use the formula to solve.

Answer:
5x
Step-by-step explanation:
. If the measures of angles A and B of triangle
ABC are each 2x + 5 and the measure of angle
C is 3x – 5, what is the measure of angle exterior
to angle A?
Using the theorem
The sum of interior angle of a triangle is equal to its exterior
Given the interior angles 2x+5 and 3x-5
Sum= 2x+5+3x-5
Sum = 2x+3x+5-5
Sum = 5x+0
Sum = 5x
Hence the measure of the exterior angle is 5x
Hi there,
the answer is option (A).
Hope it helps
Inferring that they are the only three players, all of their votes equal to 100%. If Dev gets 10%, that leaves 90% for Joe & Holly. You are now looking for a number that , when doubled adds to 90%.
Using an equation: a+2a=90
Solve for a.
3a=90 a=90/3
Now we have 10%,30%, & 60%
