13

Explanation:
85 is vertical
98 vertical
180 - 98 = 82
82 vertical
85 + 82 = 167

Answer:

13 degrees.

Step-by-step explanation:

First we calculate the other 2 angles of the triangle of which < x is a part.

The bottom angle = 85 (vertical angles are equal).

The top one = 180 - 98 = 82. ( corresponding and adjacent angles).

So angle x = 180 - (85 + 82).

= 180 - 167

= 13 degrees.

A newspaper’s cover page is 3/8 text, and photographs fill the rest. If 2/5 of the text is an article about endangered species,

Answer:

$\frac{3}{20}$

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is $\frac{3}{8}$ text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text = $\frac{3}{8}x$

Remaining part = $x-\frac{3}{8} x$

Remaining part = $\frac{8x-3x}{8}=\frac{5}{8} x$

Therefore, a newspaper;s cover page fill with Photograph = $\frac{5}{8}$

If the article about endangered species= $\frac{2}{5}$ of text

Therefore, the article about endangered species= $\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x$

Hence, the article about endangered species is $\frac{3}{20}$ of the cover page.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

GREYUIT [131]

Answer:

Decay
Decrease rate is 8%

Step-by-step explanation:

Given function:

y = 490(0.92)^x

The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.

The rate of decrease is

0.92 times

Percent decrease is

(1 - 0.92)*100% = 8%

Answer:

$D.\ \angle FOB\ and\ \angle EOC$

Step-by-step explanation:

$\angle FOC=180\textdegree\ \ \ \ \ \ \ \ \ \ as\ FOC\ is\ a\ straight\ line\\\\\angle FOC=\angle COE+\angle EOF\\\\\angle COE+\angle EOF=180\textdegree\\\\Hence\ \angle COE\ is\ supplementary\ to\ \angle EOF$

$\angle EOB=180\textdegree\ \ \ \ \ \ \ \ \ \ as\ EOB\ is\ a\ straight\ line\\\\\angle EOB=\angle FOB+\angle EOF\\\\\angle FOB+\angle EOF=180\textdegree\\\\Hence\ \angle FOB\ is\ supplementary\ to\ \angle EOF$
