Answer 1

Answer:

1. Not similar

2. Similar, ABC is similar to FED by SSS

Step-by-step explanation:

1. Not similar.

The interior angles of a triangle always have to add up to 180, and since the first triangle has angles 30 degrees and 90 degrees, you know the third angle will have to be 180 - 30 - 90 = 60 degrees.

The second triangle's third angle will have to be 50 degrees because 180 - 90 - 40 = 50 degrees.

Since the three angles of the triangle are not the same, they are not similar.

2. Similar, ABC is similar to FED by the SSS triangle similarity postulate.

First, AB is similar to FE because AB = 15 and FE = 5, so the scale factor is 3

Next, BC is similar to ED because BC = 9 and ED = 3, so the scale factor for these sides is also 3

Lastly, CA is similar to DF because CA = 12 and DF = 4, so the scal factor for this is also 3.

Since the scale factor for all of the sides is 3, these two triangles are similar.

Answer 2
Not similar. The interior triangles always have to add up to 180

In ΔQRS, the measure of ∠S=90°, QS = 11, SR = 60, and RQ = 61. What is the value of the sine of ∠Q to the nearest hundredth?

Answers

Answer:

0.98

Step-by-step explanation:

Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).

Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.

Sin(angle Q) = 60/61 = 0.98

Find the area of figure ABCDE if angles A, B, and C are right triangle

Answers

Answer:

85 ft.

Step-by-step explanation:

8*10=80 (the value of the the rectangle by itself)

then we take the values we are given and find the width and height of the triangle. Knowing it is a right triangle, we perform two equations,

15-10 (the total length of the polygon) 5 ft

and

8-6 (to find the height of the triangle, using the length where the hypotenuse of the triangle cuts off the rectangle) 2 ft

With this, we now have the length and width of the right triangle, and multiply them together to get 10. Because that formula only works on rectangles and squares, but we know that the triangle is a right triangle, we divide the 10 in half to get 5, which is the area of the triangle. Together, the value of the area for the rectangle and the triangle together result in 85 ft (remember to label units when in a written test!)

Answer:

(-3, -5)

Step-by-step explanation:

We will multiply (6a -2b = -8) by -3, and (a - 3b = 12) by 2

Thus,

-18a + 6b = 24

2a - 6b = 24

=

-16a = 48

a= -3

Then we'll substitute,

-18(-3) + 6b = 24

54 + 6b = 24

6b = -30

b = -5
