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

"Each week, a subcommittee of four individuals is formed from among the members of a committee comprising seven individuals. Two

denis-greek [22]

Answer:

140 weeks.

Step-by-step explanation:

We are being asked for the maximum number that can elapse without having 2 subcommitees with the same members and the same chair. Notice that the secretary is not mentioned in this statement, so we can ignore that position.

Now, the maximum number of weeks would be equal to the total possible combinations of subcommitees that can be formed from the 7 individuals commiteed, times the number of options that can sit at the chair possition.

The total possible combinations of subcommitees that can be formed from the 7 individuals can be expressed like the following expression. Notice that there is no a particular order to be considered, so we use the combination formula:

$\left[\begin{array}{ccc}7\\4\end{array}\right]$ = $\frac{7!}{4!(7-4)!}$ = 35

Now, each of the 4 individuals have the same probability of being chosen as the chair commitee. So, we have to multiply 4 times the number of possible subcommitees in order to arrive our answer:

x = 35 * 4 = 140

This would be the maximum number of subcommitees that can be formed with no subcommitees with the same members and the same chair occurring.

.300 + .060 + .008
You would break each number's place value down and add them in a line, in decimals, you would do the exact same.

Match the given conditions to the number of triangles that can be constructed from them. The measures of two angles are 30 degre

Maurinko [17]

Answer:

One triangle

Step-by-step explanation:

The angles being fixed at 30° and 60° cause the legs to be fixed.

For the 30° angle, one side is the given side of 12, the other side is at a fixed position.

The same goes for the 60° angle.

So both missing legs of the triangle are at fixed angles. The missing angle is 90° (if one is 30° and the other is 60°, then the last angle must add up to 180°, so it is 90°)

Since the last angle is also fixed, it means that there is only one way for the legs to intersect to cause a 90° angle, so there is only one triangle that can be formed
