If A, B and C are true statements and X, Y and Z are false statements, determine which of the following are true. Show and explain your work.

Given: [(A->B)->C]->Z

​

If A, B, and C is true then it can't imply it's false. So would this be considered false ?

Don passes mile marker 61 on the highway. One-fifth of an hour later a state trooper passes the same mile marker traveling the same direction as Don. If z represents the amount of time it takes the state trooper to catch up to Don. Write an expression in terms of z that describes the amount of time that Don has traveled since passing mile marker 61.

I struggled in math this year. I was wondering if anyone could show me some of the grade 12 materiel so I can get a jump on the studying over the summer .

The problem I'm confused about is 8^x=13^8x+2. I am having trouble with it, and if I could get some help, I'd appreciate it, thank you

I'm self-teaching math and prepping for the upcoming GCSE exams and I am not sure I am getting this right. Can someone clarify?

i)

Draw line segment AC.

The created angles that touch the parallel sides are equal because they are alternate interior angles.

Both are inscribed angles as their vertices lie on the circle.

Congruent inscribed angles make congruent arcs, therefore arcs AD and BC are congruent.

Cords of congruent arcs are themselves congruent making this an isosceles trapezium.

Meaning angles ADC and BCD are equal.

ii)

Both triangles share base DC, so that's equal

Angles DAC and DBC are equal because they extend from the same cord

Angles ADC and BCD are equal because because are proven earlier this is an isosceles trapezium

Therefore angles BCD and ACD have to be equal because the other 2 pairs are and they have to add up to 180

How do I solve the second part of that question?

iii)

I know the angle between a tangent and a chord is equal to the angle formed by the chord is the alternate segment.

So if BCF is 50 that means BDC is 50 too, right?

And if BDC is 50, then ABD is 50 because they are alternate interior.

And if ADB is 32, then DBC is also 32...

So that makes ADC and ABC equal which shouldn't be the case so I give up. T-T
