Question

Help me pls in maths​

Answer 1

a)

angle sum of quadrilateral= 36

so, w= 360 - ( 100 + 75 + 70)

w= 360 - 245

w= 115°

b)

angle sum of pentagon= 540°

so, x= 540 - ( 75 + 110 + 95 + 115)

x= 540 - 395

x= 145°

c)

angle sum of hexagon= 720°

so, y= 720 - ( 100 + 125 + 140 + 121 + 117 )

y= 720 - 603

y= 117°

d)

angle sum of heptagon= 900°

so, z= 900 - ( 125 + 138 + 138 + 133 + 137 + 105 )

z= 900 - 776

z= 124°

e)

angle sum of hexagon= 720°

so, x= 720 - ( 124 + 140 + 129 + 95 + 123 )

x= 720 - 611

x= 109°

Answer 2

a) w= 115°

b) x= 145°

c) y= 117°

d) z= 124°

e) x= 109°

f) x= 114°

g) x= 145°

h) x= 90°

i) x= 120°

j) x= 106°
