Answer:
the slope would be -1/2.
Step-by-step explanation:
If R is between Q and S then QR+RS=QS
given
QR=x+4
RS=3x-1
and QS=27
x+4+3x-1=27
combine like terms
4x+3=27
minus 3 both sides
4x=24
divide both sides by 4
x=6
sub back
QR=x+4
QR=6+4
QR=10
RS=3x-1
RS=3(6)-1
RS=18-1
RS=17
x=6
QR=10
RS=17
Answer:
6
Step-by-step explanation:
The law of cosines is useful here.
a^2 = 8^2 +11^2 -2·8·11·cos(32.2°) ≈ 36.070003
a ≈ √36.070003 ≈ 6.00583
a ≈ 6
X= 12.5, this is because you need to add 25 to the other side of the equation to make 2x = 25 and then divide both sides by 2 to get x=12.5
