Answer:
x = 50°
y = 50°
z = 80°
Step-by-step explanation:
working out x:
angles on a straight line add up to 180°
x + 130° = 180°
subtract 130 on both sides
x = 180° - 130°
x = 50°
working out y:
two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°
y = 50°
working out z:
the sum of a triangle add up to 180°
add up the angles of x and y and equate to 180°
50 + 50 + z = 180
100 + z = 180
subtract 100 on both sides
z = 180 - 100
z = 80°
height=x
length=20-2(what u cut out)=20-2x
width=30-2(what u cut out)=30-2x
so v(x)=l*w*h=x(20-2x)(30-2x)
b) (0,10)
Answer:
y= 1/3x -6
Step-by-step explanation:
you just have to plug the given values into the slope intercept formula:
y = mx +b
where M is the slope and B is the y-intercept
Answer:
well 2^6 = 64 so 8x8, 32x2 and 16x4 would all be correct
Yes☺
you are right 7 times 6 is 42 and 7 times. 8 is 56
