If the angle opposite of the height of a right angle triangle is 15 degrees and the base is 215 cm how much is the height of the triangle.

Adriveway is 60-feet long by 6-feet wide. the length and width of the driveway will each be increased by the same number of feet. the following expression represents the perimeter of the larger driveway: (x + 60) + (x + 6) + (x + 60) + (x + 6) which expression is equivalent to the expression for the perimeter of the larger driveway? a) 2(x + 66) b) 4x + 33 c) 4(x + 33) d) 4(x + 132)

X+ y = 5 ; x - y =3 solve using linear combination
