Answer:
71
Step-by-step explanation:
its an isosceles triangle, as we can tell from the sides, that means that 2 angles are the same size as well. a triangle has 180 degrees.
180-38=142
142/2=71
check
71+71+38=180
that means x=71 degrees

Items bought:
x packs of pencils
twice as many packs of erasers, number of packs of erasers = 2x
three times as many rolls of tape, number of rolls of tape = 3x
Now, we have two possible scenarios:
1- The three items cost the same:
cost of one pack of pencils = cost of one pack of erasers = cost of one roll of tape = m
total amount spent = xm + 2xm + 3xm = 6xm
2- The three items do not cost the same:
cost of one pack of pencils = m
cost of one pack of erasers = n
cost of one roll tape = p
total amount spent = xm + 2xn + 3xp = x(m + 2n + 3p)
Triangle on the left: 30 60 90 right triangle
so ratio of short leg: long leg: hypo = x : x√3 : 2x
given hypo = 4√3
so
short leg = 4√3 / 2 = 2√3
long leg = 2√3 * √3 = 6
a = 6 and c = 2√3
triangle on the right is 45 45 90 right triangle
so ratio of leg: leg: hypo = x : x : x√2
from above you know a = 6 so d = a = 6
b = 6√2
Answer
a = 6, b = 6√2, c =2√3 and d = 6
