A the slope of the line is 1
to calculate the slope m , use the ' gradient formula '
m = ( y₂ - y₁ ) /( x₂ - x₁ )
where (x₁, y₁ ) = 6, 3) and (x₂, y₂ ) = (9, 6)
m = 
= 
= 1
Answer: $180
4ft + 5ft + 4ft + 5ft = 18ft
18 x 10 = 180
Answer:
A and D are probably the answers
Step-by-step explanation:
Answer:
x = 63°
y = 45°
z = 72°
Step-by-step explanation:
<u>Points to remember</u>
1). Opposite angles of a parallelogram are equal
2). Adjacent angles of a parallelogram are supplementary
3). Sum of angles of a triangle is 180°
<u>To find the measures of given angles</u>
ABCD is parallelogram.
m<C = m<C = x = 63°
Consider triangle ABD
m<A + m< B + m<D = 180
x + 72 + y = 180
y = 180 - ( 72 + x) = 180 - 135
y = 45°
Also y + z + m<C = 180
45 + z + 63 = 180
z = 180 - 108
z = 72°
