Answer:
32 degrees
Step-by-step explanation: So they tell you BE is congruent to BC so triangle BCE is isosceles. We know that angle C is 35 degrees and the triangle is isosceles so angle E is 35 degrees too. Now we do 180-(35+35) and that equals 110 so angle B is 110. And we know that angle EBC and FBA are supplementary angles so 180-110 is 70 degrees so angle FBA is 70 degrees and you can do the same thing with angle DFB and AFB so 180-102 degrees is 78 degrees and to find angle a you just do 180-(70+78) and that equals 32 degrees so angle A is 32 degrees. :)
The answer to the question
Probability that it will snow = 0.263


Probability that it will not snow =

Answer is 737/1000
Hope this helps. - M
So 2d^2 and -2d^2 cancel each other out and then that leaves
3a-14+6a-4d collect like terms
9a-14-4d
And that’s the answer
