Question

Look at the figure.

What is the length of AB?

27 cm

33 cm

34.32 cm

24.32 cm

Answer 1

post the image please

Answer 2

you need the tan ratio...

and fine the lengths AP and PB

\[\tan 30 = \frac{10}{AP}\]

\[\tan(450 = \frac{ BP}{7}\]

then its AP + BP = AB

Answer 3

\[\tan(\theta) = \frac{Perpendicular}{Base}\]

\[\tan(30) = \frac{10}{AP} \implies AP = 10 \sqrt{3}\]

\[\tan(45) = \frac{7}{PB} \implies PB = 7\]

Just add them now:

\[\implies 10 \sqrt{3} + 7 = ??\]

Answer 4

24.32??(:

Answer 5

I am just kidding..

Ha ha..

Answer 6

Lol thats okay!(:

Answer 7

Yes you are right @kylav210

Answer 8

Answer 9

Welcome dear..

Answer 10

One more question??

The figure below shows a circular prop with two triangles labeled ABC and AOC made on it. The center of the prop is labeled O.
What is the area of the cloth required to make the circular prop?

12.56 ft2

3.14 ft2

6.28 ft2

10.32 ft2

Answer 12

Not sure but use pythagoras theorem:

\[\large r^2 + r^2 = 2^2 \implies r^2 = 2 \implies r = \sqrt{2}\]

r is the radius here..

Answer 13

So to find the area of circle use:

\[Area = \pi r^2 \implies (3.14) \times (2) = ??\]

Answer 14

6.28!? (:
