a triangle has side lengths in a ratio of 1: 1: 1.
a. what does this ratio mean?
b. what type of triangle has this side length ratio?

Step-by-step explanation:

an equilateral triangle because all the sides are equal

so the ratios are equal

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
