Question

can you please solve these two problems

Answer 1

Answer:

1) x=70°

y=60°

2) 59.68cm

Step-by-step explanation:

1) since, m||n

then, x=70°(alternate interior angles)

and y=60°(180-120)

2) perimeter of upper semicircle = PI*8

= 3.14*8= 25.12

perimeter of lower semicircle = PI*4

= 3.14*4 = 12.56

perimeter of middle rectangle = 8+8+3+3

= 22

total perimeter = 25.12+12.56+22

= 59.68cm
