PLEASE HELP For the right triangles below, find the values of the side lengths b and c.
Round your answers to the nearest tenth.

b = 1.7

c = 7.1

Step-by-step explanation:

the triangle with side 'b' is a 30-60-90° Δ where the ratio of sides, respectively, are 1 : : 2

to find 'b' we could set up this proportion:

b/3 = 1/

cross-multiply:

b = 3

b = 3 /

if we rationalize the denominator, this becomes (3)/3 which is or 1.7

the other triangle is a 45-45-90°Δ where the ratio of the sides are 1 : 1 :

if the legs are 5 then the hypotenuse is 5 or 7.1
