It looks right, but I could be wrong
A right triangle. The Origin connects 4 blocks up ON the y axis, then connects 2 on the x axis.
AB = BC, so 3x-2 = 2x+4. Also, BC = CA, so 2x+4=x+10.
Solve this system of linear equations:
3x-2 = 2x+4
2x+4=x+10 => x=6
Check: Does AB=BC? Does AB=BC?
Does 3(6)-2 = 2(6)+4? Does 16=16? YES.
Does BC = CA? Does 2(6)+4 = 6+10? YES
x = 6 (answer)
Answer:
c
Step-by-step explanation:
m<4 and m<3 is a straight angle. straight angles are equal to 180 degrees. the friend found m<3=40 and m<4 is equal to 140 degrees (im not good at explaining, sorry)
Heya !
Given expression -

Subtracting 25 both sides ,

Dividing by 3 on both sides ,

Therefore ,
