When a sign has the underline, it means it is also equal to.
for example,
x $\geq$ 10
so the solution for "x" is greater than or equal to 10

hope this helps!

How to calculate angle BCE?

Olenka [21]

Answer:

75.3 degrees ( to nearest tenth).

Step-by-step explanation:

If we take a section through the plane BCHE we get a rectangle.

BC = 2 cm and BE = √(7^2 + 3^2). ( By the pythagoras theorem).

tan < BCE = √(7^2 + 3^2) / 2.

So the m < BCE = 75.3 degrees.
