Answer:

TUA=123

Step-by-step explanation:

so first we find <TUS in terms of x

so 180-11x-2

178-11x

so now we can use the sum of a triangle's angles which is always 180 to find the angles in triangle TUS

178-11x+5x+10+58=180

178-6x=112

take 178 from both sides

-6x=-66

x=11

so we can do 11x11+2=TUA

TUA=123

there are two boxes. in the first box there are 7 cards numbered from 1 tp 7 the second box also contains 7 cards from 1-7 pick
mrs_skeptik [129]

Answer:

\frac{6}{49}

Step-by-step explanation:

GIVEN: There are two boxes. in the first box there are 7 cards numbered from 1 to 7 the second box also contains 7 cards from 1-7 pick one card from each box.

TO FIND: probability that the sum of the two two cards is at least 12.

SOLUTION:

sample case such that sum of cards is 12 : (5,7),(7,5),(6,6)

sample case such that sum of cards is 13 : (7,6),(6,7)

sample case such that sum of cards is 14 : (7,7)

Total sample case such that sum is atleast 12 =6

Total sample cases=49

probability that the sum of the two two cards is at least 12=\frac{\text{sample case in which sum is atleast 12}}{\text{total sample cases}}

=\frac{6}{49}

probability that the sum of the two two cards is at least 12 is \frac{6}{49}
