Answer:

1.

If two angles are supplementary, their sum is 180 degrees.

Check: 10 + 170 = 180

=> Maryam's claim is correct

If two angles are complementary, their sum is 90 degrees.

Check: 81 + 9 = 90

=> Ailia's claim is correct

2.

As the definition:

Vertical angles have sides that form two pairs of opposite rays.

Adjacent angles have a common side and don't overlap.

=> As provided pair of angles, they are adjacent pair of angles.

=> Ahmed's statement is wrong, Saalem's statement is correct.

Hope this helps!

Simplify negative 5 minus the square root of negative 44 negative 5 minus 4 times the square root of 11 i negative 5 minus 4 i t
Anika [276]

Answer:

-5-\sqrt{-44}=-5-2\sqrt{11}i

Step-by-step explanation:

We want to simplify:

-5-\sqrt{-44}

We rewrite the expression under the radical sign to obtain:

-5-\sqrt{4\times11\times -1}

We split the expression under the radical sign to get:

-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}

Recall that:

\sqrt{-1}=i

This implies that:

-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}=-5-2\sqrt{11}i

Therefore -5-\sqrt{-44}=-5-2\sqrt{11}i
