Remember alternative interior angles... so angle BDC is 20°  and angle BDA is 30<span>° 

This means that the side lengths are equal

Hope this helps ;)</span>

Draw the line passing through the point (3,-4) with a slope of 2/3
AleksAgata [21]
You just find the coordinate point. then, use your slope 2/3 (up 2, right 3) :)

EX: if your slope was negative, you’d do the same thing, but opposite -2/-3 (down 2, left 3)

hopefully this helps, good luck with math!! <3

(ps sorry if the drawing bothers you, but I wanted to show you as best as I could on how to solve your question :) )

scoundrel [369]
In trigonometry, the right triangle is considered a special triangle because there are derived equations solely for this type. It is really convenient when dealing right triangle problems because it is more simplified courtesy of the Pythagorean theorems. It is derived that the square of the hypotenuse (longest side of the triangle) is equal to the sum of the squares of the other two legs. In equation, that would be c² = a² + b². For this activity, all you have to do is find the sum of the squares in columns a and b. Then, see if this is equal to the square of the values in column c. Let's calculate each row:

Row 1:
3² + 4² ? 5²
25 ? 25
25 = 25

Row 2:
5² + 12² ? 13²
169 ? 169
169 = 169

Row 3:
9² + 12² ? 15²
225 ? 225
225 = 225

Therefore, all of the given values conform to a² + b² = c².

Recursive &amp; Explicit Definitions
natali 33 [55]

Answer:

T_{15} = 9565938

Step-by-step explanation:

Given

Sequence: 2, 6, 18, 54, 162,

Required

Determine the 15th term

The above sequence is a geometric sequence. So, first, we calculate the common ratio (r)

r = \frac{T_2}{T_1}

r = \frac{6}{2}

r = 3

The 15th term is calculated as thus:

T_n = ar^{n-1}

Where

a = 2 and n = 15

T_n = 2 * 3^{15-1}

T_n = 2 * 3^{14}

T_{15} = 2 * 4782969

T_{15} = 9565938

<em>The 15th term is 9,565,938</em>
