\frac{6}{4-13i}* \frac{4+13i}{4+13i}= \\ = \frac{6*(4+13i)}{16-169i ^{2} } = \\ = \frac{24+78i}{16+169}= \\ = \frac{24+78i}{185}=
= 24/185 + 78/185 i

6/(4 - 13i) = 6/(4 - 13i) * (4 + 13i)/(4 + 13i) = (24 + 78i)/(16 + 169) = 6/185 (4 + 13i)

Help 20 points + brainiest answer
katovenus [111]
2½ = 5/2

(2½ water)/(⅓ juice) = (5/2 water)/(⅓ juice) = (5/2) × (3/1) water/juice = (15/2) water/juice


(1⅔ water)/(¼ juice) = (5/3 water)/(¼ juice) = (5/3) × (4/1) water/juice = (20/3) water/juice

15/2 = 45/6
20/3 = 40/6
45/6 > 40/6
Clare uses more water. Han’s juice tastes stronger.

Answer:

The computation of the angles show that the value of sin x and cos y will be 4/5 and 3/5 respectively.

How to calculate the angles?

From the information, we've to compute the length of the hypothenuse using Pythagoras theorem.

Therefore, 4² + 3² = hypothenuse²

hypothenuse² = 16 + 9

hypothenuse² = 25

hypothenuse = ✓25.

hypothenuse = 5

Therefore, sin x = opposite/hypothenuse = 4/5

cos y = adjacent/hypothenuse = 3/5

In conclusion, the values are 4/5 and 3/5.
