Could someone please help me with this I’ve been trying to do it for an hour and I can’t figure out how.. it’s my last problem on my assignment (lesson performance task). The figure shows the latitudes of Washington, D. C. and Lima, Peru. The radius of the Earth is approximately 6,370 kilometers.

1. Find the angle at the Earth’s center between radii drawn to Washington and Lima.

2. Find the distance between Washington and Lima. Show your work.

3. A point’s longitude is a measure of its position east or west on the Earth’s surface. In order for your calculation of the distance between Washington and Lima to be accurate, what must be true about the longitudes of the two cities?

step-by-step explanation:

its wrong

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
