i don't now all of them but

3.is "A"

 

4.is "C"

* By definition, the sum of the interior angles of a triangle is 180 degrees.  

* Keeping this in mind, you have:

As you can see, the sum of the other two angles must be 108 degrees, then, let's add the angles given in each option:

A) 9°+9°=18

B) 26°+46°=72°

C)53°+55°=108°

D)72°+108°=180°

*Therefore, the answer is option C.  

5.is "B"

A triangle is called a right triangle when one of it's angles measures 90°.

We have been given the second angle as 14°.

The angles in a triangle add up to 180°.

∴ letting the third angle to be X;

X + 14° + 90° = 180°

X + 104° = 180°

X = 180° - 104°

= 76°

7. the answer is "B"

A = 41 * 14 / 2

A = 574 / 2

A = 287 cm²

So, the area of the trapezoid is 287 cm².

9. is "B"

Area = base x height

Or 356.25=14.25 x Height

Dividing both sides by 14.25

Height =25inches

.Height of the parallelogram is 25 inches. the answer is "B"

10.is "B"

the sum of any 2 sides of a triangle must be greater than the third side
