Answer:

Step-by-step explanation:
Hello There!
Remember the sum of all of the angles in a triangle is 180
So to find the missing angle we subtract the given angles from 180
180-71-38=71 so we can conclude that the missing angle (x) is equal to 71
6. X=8cm
This is because the length on the smaller triangle(4cm) needs to be doubled to fit the length of larger triangle,which will be 8cm (4 x 2 = 8)
The answer is the 2nd one… y=1/5x
Answer:
m^2+m+1
Step-by-step explanation:
- m^3 - 1= (m-1)(m^2+m+1)
- m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
- m^2+ m + 1
HCF= m^2+m+1 which is the factor of all three polynomials
