Step-by-step explanation:
For a one-way within-subjects ANOVA, the mean difference attributed to the manipulation is in the NUMERATOR, and the mean difference attributed to individual differences is in the DENOMINATOR of the test statistic.
it is 15 .................
It is an equilateral triangle, so the angles need to add up to 60 degrees each
5y = 60
5y/5= 60/5
y = 12
2x - 4 = 60
2x - 4 (+4) = 60 (+4)
2x = 64
2x/2= 64/2
x = 32
hope this helps (this is assuming it is a equilateral triangle)
