Hey there!:)
b1+b2
--------- x h =area
2
(3+5)/2h=area
8/2h=area
4(2)=area
area= 8ft squared (this is your answer)
Hope this helps! Let me know if you need more help:)
Answer:
3+2+2-1+2=8
Step-by-step explanation:
Hope this helps!
The number is -1.
5x+2 = x-2
X=-1
The given convex polygon has 7 sides
Hence its sum of interior angles is given by the formula , (number of sides-2)x180°
=> (7-2) x 180°
=> 5 x 180°
=> 900°
The sum of all angles must be equal to 900°
The given six angles are :
139°,126°,106°,129°,141°,112° , x°
=> 139+126+106+129+141+112+x = 900°
=> 753 + x = 900
=> x = 900-753
=> x = 147°
Hence 147° is the required answer.
