What is the length of leg s of the triangle below?
a. 1.7
b. 3
c. 1.5
d. √18
c. 9
d. √3

Length of leg s is 3 units.

Step-by-step explanation:

Given the 45-45-90 triangle, in which length of hypotenuse is and one leg is 3 units.

we have to find the length of other leg i.e leg s

As two angles of triangle are equal implies given triangle is isosceles.

As the two sides of isosceles triangle are equal.

Hence, the length of leg s must be equal to the length of other leg which is given 3 units.

Hence, length of leg s is 3 units.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

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.
