Answer:
Step-by-step explanation:
The sum of the remaining angles is 180-128 = 52°.
The remaining angles must be 26° each.
0=-x2+4x-2
+x2-4x+2=+x2-4x+2

x2-4x+2=0
(-4)^2-4(1)(2)
16-8
Final Answer: 8
Answer:
4. 8/15
Step-by-step explanation:
I will do #4. For dividing fractions, you multiply them together and remember to flip the second one.
Example: Instead of 2/5 divided by 3/4, it would be (2/5)(4/3), which = 8/15. Multiply the 2 and the 4 to get 8, then multiply the 5 and the 3 to get 15.
Answer:
72
Step-by-step explanation:
since the 4 is a triangle you must divide the 4 by 2 to get 2 then add 2 to 10 to get 12 and multiply 12 by 6 to get 72. Make sense?
