Answer:
x = 80
Step-by-step explanation:
We know the sum of the angles of a triangle is 180
x+y+z = 180
Since this is an isosceles triangle y=x
x +x + z = 180
We also know that x = 4z
Writing this in terms of x since we want to find angle x
z = 1/4x
x+x+1/4x = 180
Combine like terms
2x +1/4x = 180
Multiply each side by 4 to get rid of fractions
4(2x +1/4x) = 180*4
8x +x =720
9x = 720
Divide by 9
9x/9 = 720/9
x = 80
Answer:
answer id the 4th degree angle
Step-by-step explanation:
Answer:
Exact Form:
11/ 5
Decimal Form:
2.2
Mixed Number Form:
2 1/
5
Step-by-step explanation:
For the decimal, divide 11 by 5.
To get the Mixed number form, find out how many times 5 goes into 11, then then what is left over. Put the number left over the number that was dividing. 5 goes into 11 2 times, then 1 is left over, put the 1 over 5.
