Mm I don't know, why is that question? You must have an weird teacher
Answer: 180 degrees
Step-by-step explanation:
Angles on a line add to 180 degrees since they form a straight angle.
Answer:
138 is the answer
Step-by-step explanation:
In order to find the perimeter, we use this formula
P=2(l+w)
And to find the width, we use this formula
w = P/2 - L = 18/2 - 3 = 6
So the width is 6
3 × 6 = 18
So thats why the perimeter of the top triangle is 18
We do 21 ÷ 3 = 7, 7 = scale factor
To find the perimeter of the bottom triangle, we do
the width of the top rectangle times 7
so 6 × 7 = 48
So the perimeter for the bottom triangle is
P=2(l+w)=2·(48+21)=138
The answer is 22.6 for the top one and 6x+14y+13 for the second one... the coefficient for y=14
For perimeter you will add each side together so
8ft+22ft+12ft+16ft=58
So your perimeter is 58ft.
For area your going to divide the shape into 2 to get the area as this is an irregular shape, so
Base 1+base2x height / by 2
22+8 x4/2
30x4/2
120/2
60
If you’re wondering how I got 4 I subtracted 16 with 12 to know what the height was. Good luck!!
