  7 is located to the right of -2

Step-by-step explanation:

Larger numbers are to the right on a number line, so the statement that 7 is larger than -2 means ...

  7 is located to the right of -2

  The answer is DF=4 inch.

Step-by-step explanation:  As shown in the attached figure, a right-angled triangle DEF is constructed using a protractor, where ∠D=90°, DE 4 inch and ∠E=45°.

So, according to the figure, EF is the hypotenuse of the triangle.

Now, in ΔDEF

∠D + ∠E + ∠F = 180°, which gives us

∠F = 180°-∠D - ∠E = 180° - 90° - 45° = 45°.

Hence, ∠E = ∠F. Thus, DE = DF, which implies that ΔDEF is an isosceles triangle also.

Thus, DF = 4 inch.
