For the following word problems, first draw a picture and then solve the problem. 1) A 100-foot line is attached to a kite. When the kite has pulled the line taut, the angle of elevation to the kite is approximately 50°. Approximate the height of the kite. 2) The height of a radio transmission tower is 70 meters, and it casts a shadow of length 30 meters. Find the angle of elevation. 3) An observer 2.5 miles from the launch pad of a space shuttle launch measures the angle of elevation to the base of the shuttle to be 25°. How high is the shuttle at that instant? 16) x(z+3)+1+3-yz; use x=6, y=-5, and z=2 39 17) 6+q+5-(q-p)+15; use p=1, and q=1 27 18) -3÷3(a+c(b+5)-(-6+a)); use a=1, b=-6, and c=-4 -10 Simplify each expression. 19) 9x+9-1 9x+8 20) 10n-4n 6n 21) -9-6(-v+5) -39+6v 22) -10(-8x+9)-8x 72x-90 23) 1+4(2-3k) 9-12k 24) -8v+6(10+6v) 28v+60 25) 7(1+9v)-8(-5v-6) 55+103v 26) -10(x-7)-7(x+2) -17x+56 27) -2(-6x-9)-4(x+9) 8x-18 28) 9(7k+8)+3(k-10) 66k+42
