Q. A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the
klasskru [66]

Answer:

111.8 yards

Step-by-step explanation:

So by walking diagonally across the field, Patrick is making a right triangle with his path (the two legs are the width and length of the field). Let a = 50, b = 100, and c = the distance Patrick walks.

For a right triangle, we use the Pythagorean Theorem: a² + b² = c²

Since you're finding c, we can rearrange (using algebra) to get: c = \sqrt{a^{2} + b^{2}}

Fill in the values for a and b: c = \sqrt{50^{2} + 100^{2} } = \sqrt{12500} = 111.8 yards.

Ok, so x=48 so now you have to solve
3(48) + 17= EFG
3×48=144
144+17=161
so angle EFG is 161
and now you subtract 161 from 180 to get angle LMN
which is 19
BUT we still have to check
1/2 (48)-5=LMN
1/2=0.5
0.5×48=24
24-5=19
so angle LMN is 19
answers: EFG; 161
LMN; 19
