Answer:
x=3
Step-by-step explanation:
∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5
The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°
To find x, you can find ∠DBC first. *Don't forget BRACKETS
∠DBC=180-(20x+5)
∠DBC=180-(9x-2 + 40°)
Now equal the equations to each other to find x.
180-(20x+5)=180-(40+9x-2)
180-20x-5=180-40-9x+2
175-20x=142-9x
175-142=20x-9x
33=11x
x=33/11
∴x=3

Answer:
D and C
Step-by-step explanation:
1) You can cross check using desmos.
2) cos(120) is - 0.5
Answer:
The cross section of a cube is square...
and we know that ,Area of square = side²
so, Area of cross section= l²
