<h3>Given:</h3>

angle CED = 45°

angle EDC = x

angle DCE = 2x

The value of x.

<h3>Angle Sum Property:</h3>

The sum of all the Interior Angles of a triangle is 180°.

<h3>Solution:</h3>

x + 2x + 45° = 180°

or, 3x = 180° - 45°

or, 3x = 135°

or, x = 135/3 = 45°

<h2>Answer:</h2>

The value of x is 45°.

Answer:

x = 45

Step-by-step explanation:

CDE + CDE + CED =180°

x + 2x + 45 = 180

3x = 135

x = 45

If sin t = -8/17 and t is a quadrant III angle, find cot t

nirvana33 [79]

Answer:cot t = 1.875

$sin t=\frac{-8}{17}$ but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t

⇔cos t = $\sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2} }=|\frac{15}{17}|$

but t is a quadrant III angle => cos t = $\frac{-15}{17}$

=> cot t = $\frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875$

Find the product of:

Korolek [52]

Answer:

Step-by-step explanation:

(3x - 4)(2x^2 + 2x - 1)

[(3x)(2x^2 + 2x - 1)] + [-4(2x^2 + 2x - 1)]

6x^3 + 6x^2 - 3x -8x^2 - 8x + 4

6x^3 + [6x^2-8x^2] [- 3x- 8x] + 4
