Answer:
true true true true true true true true
x=30
Step-by-step explanation:
2x+x+90=180 (anglesome prop.)
3x+90=180
3x=180-90=90
3x=90
x=90/3=30
Triangles C and F
double
8 is double of 4
think of it as making the recipe twice. twice is double. :)
30
x = 7
( x - 4 )^2 + 3x
= ( 7 - 4 )^2 + 3 ( 7 )
= 3^2 + 21
= 9 + 21
= 30
