Mathematics
1 answer:
Nuetrik [128]3 years ago
4 0

Answer:

last option

Step-by-step explanation:

Sin A: opp/hyp (opposite/hypotenuse)

opposite of A is 24 and the hypotenuse is 30

write that as a fraction: 24/30

simplify and it is: 4/5

Cos A: adj/hyp (adjacent/hypotenuse)

adjacent side of A is 18 and the hypotenuse if 30

write that as a fraction: 18/30

simplify and it is: 3/5

Find the solutions of the following equations by extracting square roots 9x2-16=0 (z-2)2-36=0
natta225 [31]

The solutions of the equation 9x² - 16 = 0is 4/3 and -4/3 and that of the equation (z - 2)^{2}  - 36 = 0 is 8 and -4.

Solving the both quadratic equations by extracting square roots:

9x^{2}  - 16 = 0

⇒ 9x^{2}  = 16                                    

∴ On taking square-root of both sides, we get

\sqrt{9x^{2} } = \sqrt{16}

⇒ 3x = +4 and 3x = -4

⇒ x = 4/3 and x = -4/3

For the equation, (z - 2)^{2}  - 36 = 0, the solution is:

(z - 2)^{2}  - 36 = 0

⇒ (z - 2)^{2}  = 36

∴ On taking square-root of both sides, we get

\sqrt{(z - 2)^{2} }  = \sqrt{36}

⇒ (z - 2) = 6 and (z - 2) = -6

⇒ z = 6 +2 and z = -6 + 2

⇒ z = 8 and z = -4

The solution of the equation 9x^{2}  - 16 = 0 is 4/3 and -4/3.

The solution of the equation (z - 2)^{2}  - 36 = 0 is 8 and -4.

What is the missing reason for the 3rd step in the proof below?
lions [1.4K]

Answer:

The missing reason for the 3rd step in the proof below is;

C. Vertical angles are congruent

Step-by-step explanation:

In the two column proof, we have;

Statement   {}            Reason

1. AB ║ CD   {}           1. Given

2. ∠3 ≅ ∠7   {}           2. Corresponding angles theorem

3. ∠7 ≅ ∠6   {}           3. <u>Vertical angles are congruent</u>

4. m∠3 = m∠7   {}      4. Definition of congruence    

m∠7 = m∠6

5. m∠3 = m∠6    {}      5. Substitution

6. m∠3 ≅ m∠6    {}     6. Definition of congruence

Vertical angles are the angles formed on the opposite sides of two straight lines when they cross each other

Other vertical angles in the diagram are;

1) ∠5 and ∠8

2) ∠1 and ∠4

3) ∠2 and ∠3
