Answer:

<B = 47°

<C = 28°

b = AC = 28.0

Step-by-step explanation:

Given:

∆ABC

AB = c = 18

BC = a = 37

<A = 105°

Required:

Length of AC = b

measure of angle B and angle C

SOLUTION:

==>Use the sine rule, sin A/a = sinC/c to find the angle of C:

SinA = sin(105) = 0.9659

a = 37

sinC = ?

c = 18

0.9659/37 = sinC/18

Cross multiply

0.9659*18 = 37*sinC

17.3862 = 37*sinC

Divide both sides by 37

17.3862/37 = sinC

0.4699 = sinC

sinC = 0.4699

C = Sin-¹(0.4699)

C = 28.0° (nearest tenth)

==>Find angle B using sum of angles in a triangle:

Angle B = 180 - (105+28)

Angle B = 180 - 133

Angle B = 47°

==>Find length of b using sine rule, b/sinB = c/sinC:

SinC = sin(28) = 0.4695

SinB = sin(47) = 0.7314

c = 18

b = ?

b/0.7314 = 18/0.4695

Cross multiply

b*0.4695 = 18*0.7314

b*0.4695 = 13.1652

Divide both sides by 0.4695

b = 13.1652/0.4695

b = 28.0 (nearest tenth)

Answer:

15

Step-by-step explanation:

4x=60

60 divided by 4 = 15

Answer:

given,

base= 10

height= 8

now, area of triangle =

[tex] \frac{1}{2} \times b \times h[/tex]

or, area =

AB ║ CD,                                          Have congruent alternate interior angles

If two lines (AB and CD) and a transversal AD, form alternate interior angles, (∠1 and ∠4) that are congruent, then the two lines are parallel

The two-column proof that shows that Segment AB║Segment CD is shown in the image attached below (See attachment).

Given the image showing an isosceles triangle, ΔACD.

The two-column proof that shows segment AB || Segment CD has been provided in the table shown in the image attached below.

We know already that:

ΔACD is isosceles

∠1 ≅ ∠3

∠3 and ∠4 base angles of the isosceles triangle, therefore, ∠3 ≅ ∠4.

By substitution, ∠1 ≅ ∠4

∠1 and ∠4 are alternate interior angles, therefore, based on the Converse of Alternate Interior Angles Theorem: AB║CD

Answer:

None of them are correct. The shape in their homework is a rectangle

Step-by-step explanation:

I would be determining my answer using Length

To find the length of the sides, when you have vertices (x₁, x₂)and (y₁, y₂) we use the formula

√(x₂-x₁)²-(y₂-y₁)²

A(5, -1), B(9, 4), C(15, 1) and D(11, -4)

Side/ Length AB = A(5, -1), B(9, 4)

√(x₂-x₁)²-(y₂-y₁)²

= √(9 - 5)² + (4 - (-1))²

= √4² + 5²

= √16 + 25

= √41

Side/ Length BC = , B(9, 4), C(15, 1)

= √(x₂-x₁)²-(y₂-y₁)²

= √(15 - 9)² + ( 1 - 4)²

= √6² + -3²

= √36 + 9

= √45

Side/ Length CD = C(15, 1) and D(11, -4)

√(x₂-x₁)²-(y₂-y₁)²

= √(11 - 15)² + (-4 - 1)²

= √-4² + -5²

= √16 + 25

= √41

Side/ Length AD = A(5, -1), D(11, -4)

√(x₂-x₁)²-(y₂-y₁)²

= √(11- 5)² + (-4 - (-1))²

= √6² + 3²

= √36 + 9

= √45

From the Calculations above ,

AB = √41

BC = √45

CD = √41

AD = √45

A square and a rhombus are shapes with 4 sides and all their sides are equal to each other.

From the above calculation, we can see that

We can see that Length AB = Length CD

Length BC = Length AD

This means , the Opposite sides only are equal to each other.

Therefore, none of them is correct. The shape in their homework is a rectangle

Answer:

Pippa is right.

Step-by-step explanation:

Pippa is right because when you plot it on a graph you can see that there are no 90-degree angles and a square needs 4 of them while a rhombus has only 2 acute angles and 2 obtuse angles and that is what this shape has. That is why Pippa is right.

x^2 = 40

Find the square root of both sides

x = ±[tex]\sqrt{40}[/tex]

Answer:

13

Step-by-step explanation:

There are 6 ways to choose the first number and 5 ways to choose the second number to paint so the total number of ways is 6 * 5 = 30 but we are over counting by a factor of 2 since 1 and 6 is the same as 6 and 1 so it's 30/2 = 15, not 30. The only choices that have a product of 6 are 2 and 3 or 1 and 6 so the answer is 15 - 2 = 13.

Answer:

13 ways

Step-by-step explanation:

Total number of distinct ways to pair two faces

= C(6,2) = 6! / (2!4!) = 15

Total number of ways to pair two faces so that the product equals six

=cardinality {1*6, 2*3} = 2

Therefore

number of ways to paint two faces such that the product is not six

= 15 - 2

Answer:

probability of getting no heads: 1/ 8

probability of at least two tails: 1/4

Step-by-step explanation:

To calculate the probability of getting no heads, multiply the probability of not getting heads for each coin. A coin has two sides: heads and tails; the probability of not getting heads would be 1/2.

1. Multiply the probabilities for each coin

1/2 · 1/2 · 1/2 = 1/8

To calculate the probability of getting at least two tails, multiply the probability of getting tails for two coins and the probability of flipping either heads or tails for the remaining coin. Because it is at least two tails, the remaining coin can flip to either heads or tails.

1. Multiply the probabilities for each coin

Step-by-step explanation:

You should always multiply by the easiest choice(which I see is multiplying the 7 and the 3 to get 21

63x + 21y = -126

-24x -21y = -30

39x          = -156
