Which postulate proves that the triangles below are similar?

Mathematics
1 answer:
Molodets [167]3 years ago
3 0

Answer:

AA~

Step-by-step explanation:

These triangles are similar but not congruent. One triangle is bigger than the other, meaning none of the side lengths are the same. On the triangles, two angles are given, a 53 degree and a 90 meaning that you would us the AA rule to determine if they are similar. Which they are.

Answer:

  (-3, 3)

Step-by-step explanation:

The blanks are trying to lead you through the process of finding the point of interest.

__

The horizontal distance from T to S is <u> 9 </u>. (or -9, if you prefer)

The ratio you're trying to divide the line into is the ratio that goes in this blank:

Multiply the horizontal distance by <u> 2/3 </u>. (9×2/3 = 6)

Move <u> 6 </u> units <u> left </u> from point T.

The vertical distance from T to S is <u> 6 </u>.

Multiply the vertical distance by <u> 2/3 </u>. (6×2/3 = 4)

Move <u> 4 </u> units <u> up </u> from point T.

__

Point T is (3, -1) so 6 left and 4 up is (3, -1) +(-6, 4) = (3-6, -1+4) = (-3, 3). The point that is 2/3 of the way from T to S is (-3, 3).

Two radar stations 5.5 miles apart are tracking an airplane. The straight line distance
Vesnalui [34]

Answer:

19°

Step-by-step explanation:

I have attached an image showing this elevation.

From the image, let's first find the angle A by using cosine rule.

Thus;

8.1² = 5.5² + 13.1² - 2(5.5 × 13.1)cos A

65.61 = 30.25 + 171.61 - 144.1cos A

144.1cos A = 171.61 + 30.25 - 65.61

144.1cosA = 136.25

cosA = 136.25/144.1

cosA = 0.9455

A = cos^(-1) 0.9455

A = 19°
