Answer:

Angle DEB: 52

Angle ADB: 30

Angle CBE: 52

Angle BEC: 38

Step-by-step explanation:

Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.

A book with 650 pages has 3 pages with diagrams.

Mrac [35]

The pages that have diagrams is an illustration of proportions

0.46% pages have diagrams

<h3>How to determine the percentage</h3>

The given parameters are:

Total = 650 pages

Diagrams = 3 pages

The percentage of page that has diagram is then calculated as:

$Diagram\% = \frac{Diagrams}{Total} * 100\%$

So, we have:

$Diagram\% = \frac{3}{650} * 100\%$

Evaluate the product

$Diagram\% = \frac{300}{650} \%$

Divide

$Diagram\% = 0.46 \%$

Hence, 0.46% pages have diagrams
