Can anybody please help?

its 4 because 2 times 2 is 4, if you double the number two you get four

answer: f = 32.2m

step-by-step explanation: that is the answer

you can't solve x because it is 2 linear equation and you only have one equation

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
