Please show steps :) The area of a right triangle is 25.5 cm². What if it’s ankles measures 45°. What is the length of its hypotenuse?
A) 9.9cm
B) 7 cm
C) 8.9 cm
Or D) 10 cm

D

Step-by-step explanation:

A triangle with the angles of 45, 45, and 90 will have equivalent side lengths and a hypotenuse longer than them by a factor of . If the area of the triangle is 25.5 square centimeters, then you can find the lengths of the sides of the triangle. Since the area of a triangle is the base multiplied by the height and then divided by 2, the side lengths of the triangle must be . This means that the hypotenuse of the triangle must be , or a little over 10cm. Therefore, the answer I would pick is choice D. Hope this helps!

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
