Answer:
we know the plane line has 180°
so here it's 111°-180° = 69°
so co- interior angles are equal so 111°=the olace of 13x-6
1000/350 = $2.85
here I just divided the amount of candy bars she bought by the total cost.
Well first you must find what 71/2 is equal to:
71 / 2 = 35.5
Now you should convert this to a decimal instead of a percent. All you have to do is move the decimal two places to the left when going from percent to decimal:
35.5% = .355
Now that you know the decimal value, you want to know what number is 12 35.5% of. To do this, think, if you were wondering what is 10% of 100, you would multiply 100 by .10 so in this case since you are going the opposite way, you would divide 12 by .335, which gives you:
35.8208955224
This can be approximated to:
≈35.82
Answer:
Triangle ABC ~ CAB ~ BCA ~ ACB
Triangle AFD ~ DAF ~ ADF
Therefore, statements a) b ) c) and d) are true.
Step-by-step explanation:
X=12.5
If the perimeter is 90
90=3x+3x+15
Combine like terms
90=6x+15
Subtracts 15 from both sides
75=6x
Divide by six to get x by itself
12.5=x
