Answer:
A. 6
Step-by-step explanation:
Since, cake is of right triangled shape, so measure of its one angle would be 90° and the sum of the measures of the remaining two angles will also be equal 90°.
Therefore,
5x +10x = 90
15x = 90
x = 90/15
x = 6
In a standard normal distribution
95% of the data is within 2 standard deviations of the mean.
have a nice day! (^o^)
Step-by-step explanation:4 -2x=3x +2
4-2=3x+2x
2=5x
X=2/5
2x+4y=12
Subtract both
Put the value in eq(2)
