1 : 2

Step-by-step explanation:

this is a 30-60-90 triangle which is a special right triangle. the ratio of the sides is x: x*sqrt(3): 2x, in the order short leg: long leg: hypotenuse. so the ratio of the short leg to the hypotenuse is x:2x or 1:2

The sum of the two interior angles of the regular pentagon will be 540°

A polygon is a plane figure described by a finite number of straight-line segments connected to form a closed polygonal chain in geometry. A polygon is defined as a bounded plane region, a bounding circuit, or both.

We can also calculate the sum of the interior angles of the pentagon in the following way:

We know that the sum of the interior angles of a polygon of n sides

Sum = (n – 2) × 180°.

Sum = 3× 180°= 540°.

Hence, the sum of the interior angles of a pentagon is 540°.

Answer:

∡3 & ∡6 are same side interior angle.

∡4 & ∡6 are alternate interior angles.

∡2 & ∡8 are vertical angles.

∡1  & ∡5 are corresponding angles (because they are in the same spot).

∡1  & ∡3 are vertical angles (because they are the opposite angle of each other).

∡1 & ∡2 are supplementary angles (because they add up to 180°).

Answer:

6

Step-by-step explanation:

You can solve this using Pythagorean Theorem;

a² + b² = c²

c is always the hypotenuse or the longest length in the triangle which is always opposite to the forming 90° angle.

a and b values can be the other 2 legs, doesn’t matter which one is which

we are given;

a = 8

c = 10

a² + b² = c²

(8)² + b² = (10)²

64 + b² = 100

b² = 100 - 64

b² = 36

√b² = √36

b = 6

Therefore the answer = 6

Obviously, Ali is correct. Khamis did a mistake, he forgot the negative sign of  - 5, when he divided b. He should have let - 5b and divided it by - 5 like ali did.

Answer:

192

Step-by-step explanation:

The length is 8.3 and the width is 7.5

8.3 to the nearest whole number is 8

7.5 to the nearest whole number is 8

8 x 8 = 64

64 x 3 = 192

The whole area of the wall that Alyssa painted is 192 ft²

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

Given that, Alyssa paints 3 walls blue. Each of the walls is 8.3 feet tall and 7.5 feet wide.

Since, the length is 8.3 and the width is 7.5

8.3 to the nearest whole number is 8

7.5 to the nearest whole number is 8

Therefore, area = length × width

= 8 x 8 = 64 ft²

Area of 3 walls =

64 x 3 = 192 ft²

Hence, the whole area of the wall that Alyssa painted is 192 ft²

Answer:

$2.9

Step-by-step explanation:

Answer:

See below for answer.

Step-by-step explanation:

m ∠3 = m∠ 7       If ║ then cor. ∠s are =

m ∠2 = m∠7        Transitive     ∠2 = ∠3; ∠3 = ∠7; ∴∠2 = ∠7

The missing reason is : transitive property.

A transitive relation is defined as a homogeneous relation R over the set A, where the set contains the elements such as x, y and z, such that R relates x to y and y to z, then R also relates x to z.

As in statement 3 we have,

∠2 = ∠3

and in statement 5 we also have

∠3 = ∠7

So, by using transitive property we can write,

If a = b and b = c,

then a = c

Hence, m∠2 = m∠7 using transitive property.
