Answers

Answer:

a = 10

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is qual to the sum of the squares on the other 2 sides, that is

a² + 24² = 26²

a² + 576 = 676 ( subtract 576 from both sides )

a² = 100 ( take the square root of both sides )

a = [tex]\sqrt{100}[/tex] = 10

Step-by-step explanation:

[tex]|k+6|=3[/tex] gives [tex]k+6=3[/tex] if [tex]k + 6 \geq 0[/tex]. This gives [tex]k=-3[/tex], which is valid.

It can also give [tex]-(k+6) = 3[/tex] if [tex]k + 6 < 0[/tex]. This gives [tex]k=-9[/tex], which is valid.

Hence the solutions are [tex]k=-9 \vee k=-3[/tex].

Step-by-step explanation:

Linear pairs are supplementary. Vertical angles are congruent. An angle is the sum of its parts.

(a) C: supplementary to 138°, 180° -138° = 42°

(b) O: congruent to 138°

(c) R: supplementary to 32°, 180°-32° = 148°

(d) H: congruent to 32°

(e) S: complementary to 28°, 90° -28° = 62°

(f) O: supplementary to 122°, 180° -122° = 58°

(g) W: congruent to 122°

(h) C: supplementary to 28°, 180° -28° = 152°

(i) I: supplementary to 60°, 180° -60° = 120°

(∠TSW) E: supplementary to a right angle: 180° -90° = 90°

(∠TSU) O: half the complement of 20°, (90° -20°)/2 = 35°

(∠USW) H: complement of ∠TSU, 90° -35° = 55°

(∠RSV) A: supplement of ∠VSW = 180° -35° = 145°

__

The desired order of the letters corresponds to the sequence of angles ...

  122°, 55°, 58°, 35°, 62°, 120°, 90°, 148°, 71°, 152°, 138°, 145°, 42°, 32°

In the fraction 15/60, 15 is the numerator and 60 is the denominator.

When you ask "What is 15/60 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 15 and 60, which is 15.

Then, we divide both 15 and 60 by the greatest common factor to get the following simplified fraction:
