Answer:
are of trapezoid =1/2×height(a+b)
Step-by-step explanation:
A=1/2×8(10+20)
=4×30
=120cm*
Answer:
Yeah,its right angled traingle.
Reason:Suppose Root over 50 as hypotenuse and other two sides as base and perpendicular respectively.
By using pythagoras theorem
h^2=p^2+b^2
50=50(which is true)
Therefore it is right angled triangle..This is your required answer.
It would be 6.0x4 because the square is 6.0 on each side
Answer:
y=10x-15
Step-by-step explanation:
with the points given you know x=2 and y=5
make a new point called (x,y)
now use the formula (y-5)/(x-2)=10 (10 being the gradient)
y-5 = 10(x-2)
y-5=10x-20
add 5 to both sides
y-5+5=10x-20+5
y=10x-15
