Answer:
Angle A: 40°
Angle B: 50°
Angle C: 90°
Side A: 14
Side B: 12
Side C: 11.2 or 11 if you round to the nearest whole number.
Step-by-step explanation:
Angle A;
Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.
90-50=40
Angle A= 40°
Side C;
Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.
cos 40°= C/14
C/14= cos 40°
C/14= .8
C= .8 x 14
C= 11.2
Hope this helps! Have a great day! :)

Answer:
1, 4 or 7
Step-by-step explanation:
The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.
adding 1 gets you 30, which we know is divisible by 3.
then, instead of trying every digit, we can note that
30 , 33 , 36 , 39 ....
are divisible by 3.
But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant
so, we want to find out if we can make 29 into 30, 33, or 36
adding 1 to 29 = 30
adding 4 to 29 = 33
adding 7 to 29 = 36
So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)
<span>When you round to the <em>nearest ten</em>, you are looking for numbers like 10, 20, 30, etc. These all have a zero in the ones place. In the case of 34 34 is closest to 30</span>
