Answer 1

@Tayssir try asking one question at a time, and help on getting it solved. Usually by then, you'll understand the method your worksheet is trying to teach you.

Answer 2

@cardinal_carlo can you help me understand the first one

Answer 3

@Tayssir could I please ask you to zoom in on the first one.

Answer 4

@cardinal_carlo

Answer 5

That is a special right triangle (i.e. 45-45-90). That being said, our sides should equate each other:
\[a = 4\]
And for b, we just multiply the side-value with root two like so:
\[4\sqrt{2} = b\]

You should take time to remember your special triangles @Tayssir

Answer 6

b=5.6 ? @cardinal_carlo

Answer 7

Close.
\[4\sqrt{2} ~ \approx 5.6569\]

Although it's usually best to leave your answer in radical form. It really depends on your professor.
