Answer:
Your x angle here is supplementary to the missing angle of the triangle, the "missing angle" of the triangle is the same as <B - which is 75 degrees. So; to solve x, 180-75=x
x=105
Step-by-step explanation:
No map given but it shouldn't matter.
E is the 5th letter, L the 12th.
Start at S(6,12). End at E(10,5)
The vector between them, E-S=(4,-7)
Each unit is 1/16 of a mile, though that probably doesn't matter that much.
Doug has to stay on the grid, so has to run |4|+|7|=11 units. At 30 mi/hr that takes (11/16)/30 = 0.022916 hours.
Bert can go diagonally, so flies √(4²+7²)=√65 ≈ 8.06 units. At 20 mi/hr that takes (8.06/16)/20 = 0.025194 hours.
Answer: Doug wins
Why? Because it's quicker to cover 4+7 at 30 mph than it is to cover √(4²+7²) at 20 mph. That is, Doug is 1.5 times faster and the 1.5 times the diagonal distance is more than the grid distance.
Answer:
I think it is 1 in 12 ft.
Step-by-step explanation:
49/12
Just mulitply the top and the bottom across.
7*7/4*3
49/12
You use pemdas and they both equal to 77. So yes they are equivalent.
