Answer:
<stv=153
Step-by-step explanation:
stu+stv=180 (being a straight angle)
3b +15b+18=180
18b=180-18
b=162/18
b=9
now
<stv=15b+18
=15 × 9 +18
=135+18
=153
<stv=153°
Answer:
see below
Step-by-step explanation:
a) 2(x - 1) = 4 (x + 2)
Distribute
2x-2 = 4x+8
Subtract 2x from each side
2x-2x-2 = 4x-2x +8
-2 = 2x+8
Subtract 8 from each side
-2-8 = 2x+8-8
-10=2x
Divide each side by 2
-10/2 = 2x/2
-5 =x
b)(3 - x) (x + 2) = 0
We can use the zero product property
3-x = 0 x+2= 0
3-x+x=0+x x+2-2=0-2
3=x x=-2
