Solve the triangle in the figure.
Question options:

A)

BC = 9; m∠A = 53.1°; m∠B = 6.9°; m∠C = 90°

B)

BC = 11; m∠A = 42.8°; m∠B = 47.2°; m∠C = 90°

C)

BC = 19; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°

D)

BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°

Answers

Answer:

D)

BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°

Step-by-step explanation:

15²-12² = 9²

BC = 9

sin B = 12/15 = 0.8

∠B = 53.1°

The solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.

What is the Pythagorean theorem?

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.

The triangle ABC is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:

H² = P² + B²

The length BC will be calculated as below:-

15²-12² = 9²

BC = 9

The angle B will be calculated as below:-

sin B = 12/15 = 0.8

∠B = 53.1°

Therefore, the solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.

Line t intersects line u as shown below


What is the value of x

Answers

Answer:

x = 117 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, the angle at the top left on line t is equal to theta of the top left on line u and is equal to 117 degrees (corresponding angle)

Also the angle angle on the top left on line u will be equal to x (vertically opposite angle)

Hence the value of x = 117 degrees (vertically opposite to each other on line u)

Sanjay determined that one
vertex of a figure was mapped to its image by
translating the point 2 units left and 7 units
down. What is the rule that maps the other
vertices of the figure to their images?

Answers

Answer:

T<-2, -7> (x, y)

Step-by-step explanation:

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points. The rule that maps the other vertices of the figure to their images is T<-2, -7> (x, y).

What are coordinates?

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Given that Sanjay determined that one vertex of a figure was mapped to its image by translating the point 2 units left and 7 units down.

In order to translate coordinates, 2 units left we need to subtract 2 units from the x-coordinate of the point, while to translate the point 7 units down we need to subtract 7 from the y-coordinate of the point.

Therefore, the rule that maps the other vertices of the figure to their images is,

(x₁, y₁) = (x-2, y-7), ot it can bse written as T<-2, -7> (x, y),

where x₁ and y₁ are the coordinates of the point after translation.

Hence, the rule that maps the other vertices of the figure to their images is T<-2, -7> (x, y).
