Please help with the problem

I think it’s
1: true
2: false
3: true
4:false
5: false

Explanation:

If you are dividing a fraction, the divisor will become it's reciprocal and the division sign will change to a multiplication sign.

Solution (a):

3 ÷ 1/4 = 12=> 3 x 4 = 12=> 12 = 12 [True]

Solution (b):

7 ÷ 1/2 = 1/14=> 7 x 2 = 1/14=> 14 ≠ 1/14 [False]

Solution (c):

1/5 ÷ 4 = 20=> 1/5 x 1/4 = 20=> 1/20 ≠ 20 [False]

Solution (d):

1/2 ÷ 5 = 5/2=> 1/2 x 1/5 = 5/2=> 1/10 ≠ 5/2 [False]

Solution (e):

1/7 ÷ 3 = 1/21=> 1/7 x 1/3 = 1/21=> 1/21 = 1/21 [True]

Final Answer(s)

Option AOption E

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
