Answer:
Step-by-step explanation:
For a start simplify each of the roots:
Now simplify the expression in steps:










Answer:
s=32
Step-by-step explanation:
15x-31 = 9x+11
6x=42
x=7
2(63+11)= 2(74)= 148
180-148=32
The sum of the angles equals 180
therefore
x+(1/4x)=180
1 1/4 x = 180
x=180/ 1 1/4
x=144
1/4 x =1/4(144)=36
