She needs to be able to run 7.7 more miles a day.

In order to find this amount, we need to start by taking the amount she wants to run and subtracting what she is already able to. She wants to run 26.2 miles and can already run 18.5 miles.

26.2 - 18.5 = 7.7 miles

What is the altitude of a rhombus if its area is 50 square meters and the length on one side is 12.5 meters
SVETLANKA909090 [29]

<u>Answer:</u>

8 meters or 4 meters

<u>Step-by-step explanation:</u>

We know that for finding the area of a rhombus, there are two diagonal sides: one of which is 12.5 meters in length and the other one we'll assume to be y.

Then, we can write:

Area of rhombus = \frac{1}{2} *12.5*y

50=\frac{1}{2} *12.5*y

y=\frac{100}{12.5}

y=8 meters

If the sides of the rhombus are not internally diagonal, then we can simply use the following formula:

Area of rhombus = altitude * side

50=a*12.5

a=4 meters

Cost A=0.6489<br><br> take the inverse cosine of both sides
Stolb23 [73]
I am not quite sure what the question asks for,
But this is what i assume it wants:

Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A
cos^{-1} : It looks like this in the calculator
cos^{-1} × cos A=cos^{-1}(0.6489)
(cos^{-1} and cos cancels out)
A=cos^{-1}(0.6489)
A=49.54°
check: 
cos 49.54=0.6489 (its right!)
