vodka [1.7K]2 years ago
5 0

Answer:

x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3

Step-by-step explanation:

Subtract 15 from both sides

8x=-15

Divide 8 on both sides

Now you get your answer

x=-15/8 or -1 7/15

OR

Combine like terms

9x+15=0

Subtract 15 from both sides

9x=-15

Divide 9 from both sides

x=-15/9

Simplify

x=-5/3 or -1 2/3

HELP ME FIND THE ANGLE<br><br><br><br><br> HELP ME FIND ANGLE A
romanna [79]

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. :)
