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.

jolli1 [7]

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.

GREYUIT [131]

Answer:

  • Decay
  • Decrease rate is 8%

Step-by-step explanation:

<u>Given function:</u>

  • 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.

<u>The rate of decrease is </u>

  • 0.92 times

<u>Percent decrease is </u>

  • (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
