Use photo math , I’m sure it will help
(x+51)+(x+59)+84=180 (Sum of angles in a triangle)
2x= 180-194= -14
x=-7
Angle A: x+51=-7+51=44°
V=πr^2h=π·5^2·9≈706.85835
plz mark brainliest.
Distance = speed x time
Speed= 520÷10=52
52mi/hour
Solve by elimination
multiply top by -1
-2x + y = -4
x - y = -2
-x = -6..............so x = 6
2(6) - y = 4
12-y = 4
-8 = -y
so y = 8
(-6,8)
