Hello from MrBillDoesMath!
Answer:
3/tan(35) (approximately 4.3)
Discussion:
From plane trigonometry
tan (35) = (side opposite angle )/(side adjacent angle)
= 3 / ? (*)
Multiply both sides of (*) by ? to get
? tan(35) = 3/? * ? = 3
Divide both sides by tan(35) to get
? = 3/tan(35)
= 3 /(.700 ) approximately
= 4.3
Thank you,
MrB
Answer:
<u>21 niños</u>
Step-by-step explanation:
Para cada 6 niñas, hay 7 niños. Sabemos que hay 18 niñas entonces 18÷6 es 3. Ahora haces 7×3 y te da <u>21</u>.
For this case we can model the problem as two similar rectangle triangles.
We then have to simulate triangles:
Rewriting we have:
From here, we clear the value of x:
