To calculate the value of x, you can apply:
Tan(α)=Opposite leg/Adjacent leg
In this case, the opposite leg is "x", and the adjacent leg is 15. The angle α is 30° (α=30°)
When we substitute this values, we obtain:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/15
x=(15)(Tan(30°))
x=5√3
<span>What is the value of x?
</span>
The answer is: The value of x is 5√3
Because both angles are the same, and are in the same spot in the congruent triangles, we can set these angles up to equal each other:
Add x to both sides:
Subtract 4 from both sides:
Divide both sides by 4 to get x by itself:
The value of x is
17.
Answer:
21x-15
Step-by-step explanation:
Use the distributive property:
3×7x=21x
3×5=15
Don't forget the - sign!!!
So,
3(7x - 5) = 21x - 15
Answer:
Final answer is .
Step-by-step explanation:
Given equation is .
Now we need to solve that equation for t when .
or ,
or ,
or ,
Given that t>0
so that means t=-5 is not possible.
Hence final answer is .
