x=120

y=60

Step-by-step explanation:

So it states that this is an equilateral triangle which means that all of the angles in this triangle or the same

the sum of all the angles is equal to 180 so to find y we divide 180 by 3

180/3=60

y=60

we notice that its supplementary to the angle that measures 60 and supplementary angles add up to equal 180 so to find x we subtract 60 from 180

180-60=120

x=120

Ok now this one i am 100% confident in my answer

X = 120

Y = 60

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
