The first number is 5 and the second number is 7
It is is a parallelogram, hence we have to face sides equal in length and the opposite angles are also the same. From the given above we have:
ab=14 and its opposite side cd=14
bc=20 and its opposite side da=20
Solving for the diagonal measurement bd, we have consecutive angles are equal to 180°
∠A+∠B=180°
∠A=180°-54°
∠A=126° , ∠B=54° ,∠C=126° and ∠D=54°
bd²=ab²+da²-2(ab)(da)cos126°
bd²=14²+20²-2*14*20cos126°
bd=30.42 unit
Solving for the angle dbc, we have
cos dbc=bc²+bd²-cd²/a*bc*bd
cos dbc=20²+30.42²-14²/2*20*30.42
dbc=21.76°
Because they react to iron and from rust
hope this helps
The geometric figures without measurable quantity:
- A line is infinite and have no measurable length.
- A point is a zero dimensional.
- A ray is semi-infinite. It has a beginning but no end.
An angle and a line segment are measurable.
Answer:
B. Angle
D. Line segment.
2/3+1/3x=2x
2+1x=6x
x-6x=-2
-5x=-2
x=2/5
