How do I fine the perimeter of these triangles?
arsen [322]

constant of proportionality => COP

3: P(triangle ABC) = 84

COP = 18/15 = 1.2

Since you are finding the larger triangle, multiply the other numbers by 1.2

25 * 1.2 = 30

28 * 1.2 = 33.6

17 * 1.2 = 20.4

add them all up (answer up top)

5: P(triangle ABC) = 61.2

COP = 9/5 = 1.8

Since you are finding the larger triangle, multiply the other numbers by 1.8

9 * 1.8 = 16.2

13 * 1.8 = 23.4

12 * 1.8 = 21.6

add them all up (answer up top)

6: P(triangle RST) = 110

RP and PT are congruent, this means that PT is also 20

COP = 40/20 = 2

Since you are finding the larger triangle, multiply the other numbers by 2

25 * 2 = 50

20 * 2 = 40

10 * 2 = 20

add them all up (answer up top)

In the figure below, a shaded polygon, which has equal sides and equal angles, is partially covered with a sheet of blank paper.
Zepler [3.9K]

Answer:

The polygon has 9 sides ⇒ D

Step-by-step explanation:

This is a tricky question

∵ The shaded figure is a quadrilateral

∴ The sum of the measures of its angles is 360

∵ Its angles are <u>x, y, and two vertices of the polygon</u>

∵ All angles of the polygon are equal in mesures

∴ x + y + m of 2 vertices = 360°

∵ x + y = 80

→ Substitute the value of x + y above by 80

∴ 80 + m of 2 vertices = 360

→ Subtract 80 from both sides

∴ m of 2 vertices = 280

→ Divide the two sides by 2

∴ m of 1 vertex = 140°

∴ The measure of each angle of the polygon is 140°

<em>The sum of the measures of the </em><em>interior angle and the exterior angle</em><em> at any vertex of the polygon is </em><em>180°</em>

∵ m of interior ∠ + m of exterior ∠ = 180° ⇒ at any vertex

∴ 140 + m of exterior ∠ = 180°

→ Subtract 140 from both sides

∴ m of exterior ∠ = 40°

∴ The measure of each exterior angle is 40°

<em>The </em><em>sum </em><em>of the measures of the </em><em>exterior angles</em><em> of any polygon is </em><em>360°</em>

∵ The measure of each exterior angle of the given polygon is 40°

∴ The number of the angles of the polygon = 360 ÷ 40 = 9

∵ The number of the angles of the polygon = the number of its sides

∴ The polygon has 9 sides
