Answer:

Step-by-step explanation:

Given

Balloon in the east makes an angle of elevation of $36^{\circ}$ and is at height of 461 m

Balloon in the west makes an angle of elevation of $51^{\circ}$ and is at height of 296 m

Erica height is 1.6 m tall so net altitude of Red balloon is 459.4 m

and net height of Blue balloon is 294.4 m

using trigonometry

$\tan 36=\frac{459.4}{d_1}$

$\tan 51=\frac{294.4}{d_2}$

$d_1=632.30 m$

$d_2=238.4 m$

Distance between two Balloons

$d=d_1+d_2$

$d=870.70 m$

maksim [4K]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

If you have completed $5$ questions, you still have $25-5=20$ more questions to answer. We need to find what fraction $20$ is of $25$ , if that makes sense. A fraction is simply a part over a whole. In this case, the part is $20$ and the whole is $25$ . Therefore, the fraction we are looking for is $\frac{20}{25}$ , which simplifies to $\frac{4}{5}$ . Hope this helps!
