Answer:

N.14 ABC = 5x+20, N.15 ABE = 90. N.16. 123, 29, 28. N.17 K = 80

Step-by-step explanation:

Because of vertical angles, 5x+20 = 3x+66.

5x=3x+46

2x = 46

x = 23

Sum of angles in a circle is 360

360-135-135=180

ABE = CBD because vertical angles.

180 / 2 = 90

16.

Sum of angles in triangle is 180

180=123-x-2-x-3

x = 31

123, 29, 28.

17.

Sum of angles in triangle is 180

180-72-28 = 80

K = 80

Number 2 I need help on how to solve it
Hunter-Best [27]

Let's simplify the following expression:

\text{ }\frac{\text{ \lparen2x}^4\text{ - y}^6\text{z}^{-4})^2}{\text{ 2x}^2\text{z}^3}\text{ }\cdot\text{ }\frac{\text{ 6x}^5\text{y}^{-4}\text{z}^{-5}}{\text{ \lparen2x}^6\text{y}^3\text{z}^{-3})^2}

We get,

\text{ }\frac{(\text{2x}^4\text{ - y}^6\text{z}^{-4})^2}{\text{ 2x}^2\text{z}^3}\text{ }\cdot\text{  }\frac{6x^5y^{-4}z^{-5}}{(2x^6y^3z^{-3})^2}\text{ }\frac{(2x^4-y^6z^{-4})^2(6x^5y^{-4}z^{-5})}{(2x^2z^3)(2x^6y^3z^{-3})^2}\text{ }\frac{(4x^8\text{ - 4x}^4y^6z^{-4}\text{ + y}^{12}z^{-8})(6x^5y^{-4}z^{-5})}{(2x^2z^3)(4x^{12}y^6z^{-6})}\text{ }\frac{24x^{13}y^{-4}z^{-5}\text{ - 24x}^9y^2z^{-9}\text{ + 6x}^5y^8z^{-13}}{8x^{14}y^6z^{-3}}

Two complementary angles are in the ratio 7:8. What is the measure of the larger angle?
yan [13]

Answer

<h3>48°</h3>

Step-by-step explanation:

We know that sum of complementary angle adds to 90°

Let the angles be 7x and 8x

<u>First </u><u>of </u><u>all,</u><u> </u><u>finding </u><u>the </u><u>value </u><u>of </u><u>x</u>

\sf{7x + 8x = 90 °}

Collect like terms

⇒\sf{15x = 90 °}

Divide both sides of the equation by 15

⇒\sf{ \frac{15x}{15}  =  \frac{90}{15} }

Calculate

⇒\sf{x = 6 °}

The value of X is 6°

<u>Now,</u><u> </u><u>substituting </u><u>/</u><u> </u><u>Replacing</u><u> </u><u>the </u><u>value </u><u>of </u><u>x</u>

⇒\sf{7x = 7 \times  6 = 42}

⇒\sf{8x = 8 \times 6 = 48}

The measure of larger angle is 48°

Hope I helped!

Best regards!!
