Height: a six-foot person walks from the base of a
broadcastingtower directly toward the tip of the shadow cast by the
tower. whenthe person is 132 feet from the tower and 3 feet from
the tip ofthe shadow, the person's shadow starts to appear beyond
the tower'sshadow.

a) draw a right triangle that gives a visual representation of
theproblem. show the known qualities of the triangle and use
avariable to indicate the height of the tower.

b) use a trigonometric function to write an equation involving
theunknown quality.

c) what is the height of the tower?

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

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?
