What two measurement could make up a complementary angle when one angle is 8 degrees more than the other?

1 answer:

7 0

Complimentary angles add up to 90 degrees

x + y = 90
x = y + 8

y + 8 + y = 90
2y + 8 = 90
2y = 90 - 8
2y = 82
y = 82/2
y = 41

x = y + 8
x = 41 + 8
x = 49

so ur angles are : 41 and 49

Katen [24]

Answer: she has $20 left now.

Step-by-step explanation:

The total amount of money that Kathryn had yesterday was 105 dollars.

She first spent 1/3 of it at the mall. This means that the amount of money that she spent at the mall is

1/3 × 105 = $35

The amount left after her shopping would be 105 - 35 = $70

Later, she went to the movies and spent 5/7 of what was left after her shopping. This means that the amount of money that she spent at the movies is

5/7 × 70 = $50

The amount that she has left now is

70 - 50 = $20

lesantik [10]

Answer: SECOND OPTION.

Step-by-step explanation:

For this exercise it is important to remember "Rigid transformations".

Rigid transformations are those transformation that preserves length. These are the following:

- Reflection.

- Tanslation.

- Rotation.

According to the information given in the exercise, the triangle JKL was translated 12 units vertically and then reflected over the y-axis to create triangle J'K'L'. Therefore, JKL and J'K'L' are congruent.

Knowing the above, you can set up the following equation:

$2x-4=8$

The final step is to solve for "x" in order to find its value. You get that this is:

$2x=8+4\\\\x=\frac{12}{2} \\\\x=6$
