Answer:

78

Step-by-step explanation:

complements = 90

x + 12 = 90

-12. -12

× = 78

If two angles are <u>complementary</u>,

then the sum of their measures is 90 degrees.

If two numbers add to 90, we can represent those numbers as <em>x</em> and <em>90 - x</em>.

So we will call one of our angles x and its complement as 90 - x.

So we have 90 - 12 which is 78.

So the complement of a 12° angle is a 78° angle.

What are the remaining angle measures if the figure is to be a parallelogram?
Kobotan [32]

Answer:

We conclude that:

m∠B = 101°

m∠C = 79°

m∠D = 101°

Step-by-step explanation:

Given the parallelogram ABCD

We know that a parallelogram has opposite angles that are congruent.

Here,

The angles ∠A and ∠C are opposite angles.

Thus,

  • ∠A = ∠C

The angles ∠B and ∠D are opposite angles.

Thus,

  • ∠B = ∠D

<u>Determining the measure of angles of a parallelogram:</u>

As

∠A = 79°

We know

  • ∠A = ∠C

Thus, the measure of the angle ∠C is:

m∠C = 79°

We know that the sum of the measure of two consecutive angles is 180°.

As ∠A and ∠D are consecutive angles, so

∠A + ∠D = 180°

substituting ∠A = 79° in the equation

79° + ∠D = 180°

subtracting 79° from both sides

79° + ∠D - 79° = 180° - 79°

∠D = 101°

Thus, the measure of the angle D is:

m∠D = 101°

We know that the angles ∠B and ∠D are opposite angles.

Thus,

  • ∠B = ∠D

so if m∠D = 101° then ∠B is also 101°.

Therefore, the measure of angle B is:

m∠B = 101°

Hence, we conclude that:

m∠B = 101°

m∠C = 79°

m∠D = 101°

The original price of a Shirt was $45. In sales, the shirt is reduced to $32.50. Calculate the percentage reduction.
Klio2033 [76]

Answer:

27.8%

Step-by-step explanation:

\frac{32.5}{45} =0.722

0.722 = 72.2%

The % reduction is:

(100-72.2)% = 27.8%

Hope this helps

Seven times a number is equal to 12 more than 3 times the number. find the number.
ankoles [38]

Answer:

the number is 3

Step-by-step explanation:

seven times a number is equal to 12 more than 3 times the number

7*n = 12+3*n

7n=12+3n

subtract 3n from each side

7n-3n = 12+3n-3n

4n = 12

divide each side by 4

4n/4 = 12/4

n =3
