Answer:
6a. x=80 6b. x=30
Step-by-step explanation:
a. x=80
b. x=30
Use the exterior angle theorem: as shown in the picture
# a
25+x=105
x=80
#b
2x+(3x+2)=152
5x+2=152
5x=150
x=30
When writing the equation keep in mind that 7 + x is said as a term that is squared so it has to be squared while it's still together; (7 + x)².
45000
multiply by 10000 for kilo-deci
a=24
= -4
-a= -4*6
-a= -24
a= 24
