Ineed on this and my last question

The Value of t from given convex polygon is 41.

Step-by-step explanation:

Let us consider,

a=61°.

b=2t.

c=3t.

d=42°.

e=52°.

The sum of exterior angles of convex polygon is always 360°.

a+b+c+d+e=360°.

The exterior angles of any convex polygon is same as if any angle drawn inside a circle.

Steps to reform the angles:

Step 1: Draw the ∠a as given in the original diagram.

Step 2: The ∠b is adjacent to ∠a 's end and draw a parallel line of ∠b in the ∠a. The angle measure will also be same.

Step 3: Continue the same for next angles ∠c,∠d and ∠e.

(refer the image dotted lines are the parallel lines.)

⇒ 61°+42°+52°+2t+3t=360°.

155°+5t=360°.

5t=205°.

t=41°.

Also,

∠b=82°.

∠c=123°.

Check,

61°+82°+123°+42°+52°=360°.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
