Ian is trying to estimate the distance across the lake d. he knows the measures shown in the diagram. which estimate is closest to the distance d ?

 The estimate is closest to the distance d is 4.2 miles

Step-by-step explanation:

In the given image, we can see that there is a right triangle, in which d is the side opposite to the right angle (largest angle in the triangle) which means its the longest side of the triangle.

[Since side opposite to the larger angle is larger]

Therefore, by Pythagoras Theorem we have

The estimate is closest to the distance d is 4.2 miles.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
