The answer is A. 5 is not an even number, so both events can't take place together.
Answer:
-4
Step-by-step explanation:
Cube Root is an odd number so your answer will still be negative in the end. 4x4x4= 64 so cube root 64 will be -4
Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.
We can solve for x for the other 3 options by setting up this equation:
7x+2 + 4x+7 + 8x = 180 | Simplify
19x + 9 = 180 | Subtract 9
19x = 171 | Divide by 19
x=9
Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72
Looking at the options again, we can see that A, B, and D are true, leaving C to be false.
The sum of the 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48 = 42 degrees.
