What is the sum of the interior angle measure of a 13-sided polygon?
The sum of the interior angle measure of a 13-sided polygon is 1980 degrees. It is solved by doing: 180(s-2) 180(13-2) 180(11) = 1980 degrees *s- meaning sides*
What is 17 times s?
17 times s is simply 17s. For an integer value, you need to first find the value of s.
What is the measure of each interior angle of a regular hexagon to the nearest tenth?
The total number of degrees in any regular polygon is calculated by (S-2) * 180º, where S = the number of sides. So, for a hexagon the total is 4 * 180º = 720º, and the measure of each interior angle is 120º, or 1/6th of the total.
What is the total surface area of the rectangular prism shown?
To calculate the total surface area of a rectangular prism, you need to find the sum of the areas of all six faces. The formula for the total surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Measure the length, width, and height of the rectangular prism, plug the values into the formula, and perform the necessary calculations to find the total surface area.
If the measure of an angle equals twice the measure of its supplement what is the measure of the angle?
120 Consider: You know that the supplement of an angle is equal to 180 minus the angle. You also know that an angle is twice it's supplement. Now, if you think of angle as being "A", and it's supplement being "S", then we can re-express the above statements like so: S = 180 - A A = 2S Then logically, we can replace the "S" in the second equation with the value we have for it in the first one: A = 2( 180 - A) and then solve that equation: ∴ A = 360 - 2A ∴ A + 2A = 360 ∴ 3A = 360 ∴ A = 360/3 ∴ A = 120
Find the measure of angle s if these triangles are similar?
We can't even begin to do that without seeing the picture.
The S's in the SSS Similarity Theorem states that two triangles are similar if they have proportional sides?
three
The S's in the SSS Similarity Theorem state that two triangles are similar if they have three proportional what?
Sides
How many triangles will the diagonals make inside the square?
For a square with side S. There will be the 4 small triangles each with sides {S/sqrt(2),S/sqrt(2),S}. Then also you can 'see' 4 larger triangles, each with sides {S,S,S*sqrt(2)}
What are the 5 ways to prove a triangles congruency?
A s a, s s s, a a a, a a s, & s a s
What is the similarity postulate or theorem that applies.David drew PQR and STU so that P S PR 12 SU 3 PQ 20 and ST 5. Are PQR and STU similar?
Similar SAS-apex
How do you make two triangles congruent?
By the property of congruent (s s s) s as RHS a s a.
Two similar rectangles have sides in ratio to two thirds what is the ratio of the perimeters?
Theorem: If two similar triangles have a scalar factor a : b, then the ratio of their perimeters is a : bBy the theorem, the ratio of the perimeters of the similar triangles is 2 : 3.For rectangles, perimeter is 2*(L1 + W1). If the second rectangle's sides are scaled by a factor S, then its perimeter is 2*(S*L1 + S*W1) = S*2*(L1 + W1), or the perimeter of the first, multiplied by the same factor S.In general, if an N-sided polygon has sides {x1, x2, x3....,xN}, then its perimeter is x1 + x2 + x3 + ... + xN. If the second similar polygon (with each side (labeled y, with corresponding subscripts) scaled by S, so that y1 = S*x1, etc. The perimeter is y1 + y2 + ... + yN = S*x1 + S*x2 + ... + S*xN = S*(x1 + x2 + ... + xN ),which is the factor S, times the perimeter of the first polygon.
How do you find the perimiter of a shape?
Run a piece of string round the edge and then measure it
How would you work out The perimeter P of similar triangles varies directly as the length of a side S If P equals 18 when S equals 4 what is the value of P when S equals 6?
S is increased from 4 to 6: a multiple of 6/4 = 1.5 So P, which is directly proportional to S, increases from 18 to 18*1.5 = 27
How many triangles are formed by drawing diagonals from one vertex of a polygon with fifty sides?
use the formula s-2 (s=sides) there are 2 triangles in a square, which has 4 sides:4-2=2 there are 3 triangles in a pentagon, which has 5 sides:5-2=3 so, there should be 48 triangles in a shape with 50 sides:50-2=48
