B, C, and D.

All you have to do is substitute 8 in these equations for the easy answer.
A) 8 + 11 = 15 (False, it equals 19)
B) 1 = 8 / 8 (True)
C) 15 + 8 = 23 (True)
D) 42 = 7(8) (False, 7 times 8 equals 56)
E) 8 - 5 = 3 (True)

What you put is correct because two negatives make a positive so it would be 5 + 7 making it the greatest value

Answer: 24, 24, 47

Step-by-step explanation:

In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations.

a + b > c & a + c > b & b + c > a

23 + 28 = 51 which is NOT greater than 55

15 + 30 = 45 which is NOT greater than 45

8 + 17 = 25 which is NOT greater than 25

24 + 24 > 47 & 24 + 47 > 24 & 24 + 24 > 27

all combinations are true so these side lengths can form a triangle

Answer:

A = 58.7 degrees

B = 66.9 degrees

C = 34.1 degrees

Step-by-step explanation:

For <A:

Tan A = $\frac{opposite}{adjacent}$

Tan A = $\frac{23}{14}$

Tan A = 1.6

A = $Tan^{-1} 1.6$

A = 58.7 degrees

For <B:

Sin B = $\frac{opposite}{hypotenuse}$

Sin B = $\frac{23}{25}$

Sin B = 0.92

B = $Sin^{-1} 0.92$

B = 66.9 degrees

For <C:

Sin C = $\frac{opposite}{hypotenuse}$

Sin C = $\frac{14}{25}$

Sin C = 0.56

C = $Sin^{-1}0.56$

C = 34.1 degrees
