Answer:
Step-by-step explanation:
- A = 1/2(b₁ + b₂)h
- A = 1/2(8 + 4)*6 = 36 m²
For this you need to know your angles in parallel lines.
3y will equal 87 as they are opposite angles and opposite angles are equal.
So y = 87/3
We can use the knowledge that angles in a straight line (in parallel line diagrams) will add up to 180. Therefore we do 180-87= 93. Now we know 3x=93 because just like the first example they are opposite angles. Now we know x=93/3.
(I didn’t have a calculator on me so you’ll have to work out the final result. Also I recommend looking into angles in parallel lines. I tried my best to explain so I hope you understand the jist of what I was trying to say.)
Proportionally? Not sure. But here is a way to find out the value of x
50° + 2x+40 +4x+8 = 180°
Combine like terms
50°+ 6x + 48=180
(now subtract 50° from both sides)
6x + 48 = 130°
(now subtract 48 from both sides
6x=82°
x= 13.6666667° (repeating decimal)
