Are the following triangles similar? Justify your answer.

FinnZ [79.3K]

Yes they are similar because one they're both 90 degree angles, and two if you divide 12÷8 it'll equal 1.5
Same thing with the other side. If you divide 36÷24 it'll equal 1.5
and this shows proof of similarity since its like half the sides, but they both have the same angles.
(Sides doesn't matter, its the angles)

QUESTION 20

atroni [7]

.Answer:

The answer is below

Step-by-step explanation:

The patient loses 1 kg every week for 5 weeks.

1 kg = 2.2 lbs

Therefore the patient loses 2.2 lbs every week for 5 weeks.

a) The weight of the patient after 5 weeks = 245 lbs. - (5 weeks)(2.2 lbs per week)

The weight of the patient after 5 weeks = 245 lbs. - 11 lbs. = 234 lbs.

b) The weight of the patient after 5 weeks = 245 lbs. - 11 lbs. = 234 lbs.

1 kg = 2.2 lbs.

234 lbs. = 234 lbs. * 1 kg per 2.2 lbs. = 106.36 kg
