Answer:
Only A. a=3
Step-by-step explanation:
Because since 7+a<11 then that means a have to be 3 or below... good luck!
A) a=3
When a=3 7+3=10 which satisfy that 7+a<11 in which 10<11
120°
angle T + 60°=180° [:. being linear pair ]
or , angle T = 180°-60°
or,angle T = 120°
119°
(Vertical angles)
x and 2x+1
2 units
x= 2×4/4 = 2 units
Slope = rise / run
so answer is
C. 1
