Hey there! :D

We know that the triangles are not similar. If they were, they would have the same angles. The interior angles are not congruent. We can rule out choice "B" and "C".

Just because they have one equal angle does not make them similar. We can rule out "D".

"A" is the best answer.

I hope this helps!

m∠AOC = m∠AOB + m∠BOC

We have m∠AOC = 19°, m∠AOB = 4x - 15 and m∠BOC = 2x + 10. Substitute:

19 = (4x - 15) + (2x + 10)

19 = (4x + 2x) + (-15 + 10)

19 = 6x - 5 add 5 to both sides

24 = 6x divide both sides by 6

4 = x

m∠BOC = 2x + 10 → m∠BOC = 2(4) + 10 = 8 + 10 = 18

m∠AOB = 4x - 15 → m∠AOB = 4(4) - 15 = 16 - 15 = 1

<h3>Answer: c. m∠BOC = 18°, m∠AOB = 1°</h3>

Find the quotient. Write your answer in standard form. : 3-i/3+i

s344n2d4d5 [400]

The answer is C. 4/5 - 3/5 i

$\frac{3-i}{3+i} = \frac{(3-i)(3-i)}{(3+i)(3-i)} \\ \\ 
(a+b)(a-b) = a^{2} -b^{2} \\ \\ 
\frac{(3-i)(3-i)}{(3+i)(3-i)}= \frac{ (3-i)^{2} }{3^{2}-i^{2} } \\ \\ 
(a-b)^{2} =a^{2}-2ab+b^{2} \\ \\ 
 \frac{ (3-i)^{2} }{3^{2}-i^{2} } = \frac{3^{2}-2*3*i+i^{2} }{3^{2}-i^{2} } = \frac{9-6i+i^{2}}{9-i^{2}} \\ \\ 
i = \sqrt{-1} \\ i^{2}=-1 \\ \\ 
\frac{9-6i+i^{2}}{9-i^{2}} = \frac{9-6i-1}{9+1} = \frac{8-6i}{10}= \frac{8}{10}- \frac{6i}{10}= \frac{4}{5}- \frac{3}{5}i$
