when you get this kind of exercise, you find need to find y or x in one of the exactions and fill it in in the other, however in this exercise the two y's are already given so all you need to do is replace the y in one of the exactions with the other exactions like this:
(keep in mind, you need to keep writing both of the exactions over again, otherwise you'll lose an exaction. and we'll need it later on)
y=-2x+6
y=3x-4
y=-2x+6
-2x+6=3x-4
y=-2x+6
-2x-3x=-4-6
y=-2x+6
-5x=-10
y=-2x+6
x= 2
and now replace the x in the first exaction with the x that we found:
y=-2(2)+6
x=2
y=-4+6
x=2
y=2
x=2

Answer:
Try 7986
Step-by-step explanation:
(a+b) × height ÷ 2
(a+b are the parallel sides)
102+140=242 ×66= 15972 ÷2= 7986
Answer:
Acute angle, right angle, obtuse angle and reflex angle.
Step-by-step explanation:
Acute angle -
0° < θ < 90°
Right angle -
θ = 90°
Obtuse angle -
90° < θ < 180°
Reflex angle -
θ > 180°
