Hello from MrBillDoesMath!
Answer:
3
Discussion:
Let the number be "n",
2n + 15 = 21 => subtract 15 from both sides
2n = 21 - 15 = 6 => divide both sides by 2
n = 6/2 = 3
Check: Start with 3. Double it (gives 6), add 15 to it ( 6 + 15) which gives 21/
Thank you,

Answer:
A
Step-by-step explanation:
This can be easily understood using the triangle inequality theorem:
"In a triangle, the combined lengths of any two sides must always be greater than the length of the third side."
- Is 10+5 greater than 4? YES
- Is 10+5 greater than 5? YES
- Is 5+4 greater than 10? No!
Since all of them doesn't hold true, we cannot make any triangle. The answer is A, 0.
Answer:
tan=0.75
Step-by-step explanation:
We know sin=opp/hyp, so 21 is the opposite side length in relation to theta.
To figure out tan, we need to know what the adjacent angle is because tan=opp/adj
21 squared= 441
35 squared =1225
1225-441= 784
The square root of 784 = 28
Now that we know both the opp and adj sides, we can solve for tan.
21/28= 0.75
