Question

Can you please help me with no. 34&35 solutions step by step

Answer 1

Answer:

35) y=40

34) 138

Step-by-step explanation:

35) if a polygon has 5 sides then the sum of all internal angles =(n-2)*180=(5-2)*180=3*180=540

so add all of the angles 3y+3y/2+2y+140+180-y=540

4y+3y/2=540-140-180=220

11y/2=220

11y=440

y=440/11=40

y=40

34) let's say width =x

so length =2x

so area =2x*x=1058

2x^2=1058

x^2=529

x=23

so perimeter =2(2x+x)=2*3x=6x

so 6x=6*23=138cm
