Answer:

Yoy answer is x=10

Step-by-step explanation:

We already know what ∠GEF is 23°

so you would have to create an equation like this 23+(5x+1)=7x+4

you add 23+1=24 and get 5x+24=7x+4 subtract 5x on both sides

24=2x+4 subtract 4 on both sides

20=2x divide 2 x=10

∠DEF=7(10)=70+4=74

∠DEG=5(10)=50+1=51

To check 51+23=74

What is 12 6/13 rounded to the nearest whole numbers
Natalka [10]
So, first determine what half of the denominator or bottom number would be.
   Half of 13 would be 6.5 (Do 13 divided by 2).
Next, see if the numerator or top number on the fraction is smaller, the same, or bigger than that number.
   Since 6.5 is bigger than 6, the numerator would be smaller.
If it is smaller, keep the whole number (in this case 12) the same. If it is the same or equal, round up (in this case 13).
   Since 6 is smaller than 6.5, you keep 12 the same.
   Your answer would be 12.

Hope this helped!
