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.
Answer:
Step-by-step explanation:
m∠2 = 180° - 113° = 67°
X+2 / y-1 =2
to leave y form
x+2 / y-1 =2
x y-1 x y-1
x+2 = 2y-2
+2 +2
x+4 = 2y
/2 /2
x/2+2=y
you have to break the shape into parts and find the are of each part. so 2 times 2 to find the area of the square part and 2 times 1 times one half to find the area of the triangle part. then you add them together to get the total area
