Given that ∠CEA is a right angle which has been bisected by BE, then:
∠CEB=∠BEA
thus each angle will be complementary to each other, hence the size will be:
90/2=45°
hence the correct statement.
<span>m∠CEB = 45°</span>

Answer:

m∠CEB = 45°  is true.

Step-by-step explanation:

We are given that,

∠CEA = 90° and BE bisects the ∠CEA.

Since, we know,

'When a line bisects an angle, it divides the angle into two equal parts'

So, we get,

∠CEB = ∠BEA = \frac{90}{2} = 45°

So, from the options we see that,

Options A, B and D cannot be true. So, only option C is correct.

That is, m∠CEB = 45°

Answer:

277cm²

Step-by-step explanation:

Base = 9x8=72

There are 2 triangles with a bottom edge of 9 and a slant height of 13:

1/2(9)(13)=58.5

There are 2 triangles with a bottom edge of 8 and a slant height of 11:

1/2(8)(11)=44

72+58.5+58.5+44+44=277cm²

Answer:

5\sqrt{8}

24\sqrt{3}

Step-by-step explanation:

To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

\sqrt{200}=\sqrt{25*8}  =\sqrt{25}*\sqrt{8}= 5*\sqrt{8}   =5\sqrt{8}

and

4\sqrt{108}=4\sqrt{27*4}  =4*\sqrt{27}*\sqrt{4}=4* \sqrt{9} *\sqrt{4}*\sqrt{3}    =4*3*2*\sqrt{3}=24\sqrt{3}

Pls help

Answer:

If you go to fill up your car, the amount of gasoline in your tank influences how much you pay. The amount is a volume calculation, regardless of whether you fill up with gallons or liters of gasoline or other fuels. On a lesser scale, when filling a gas can to transfer to another vehicle or utilize the gas to power another device, volume is used to calculate the amount needed.

Hope this helps!
