If <span>ZW is an altitude of △XYZ, then m</span>∠ZWY = 90°
3a + 5 + 5a + 13 = 90
8a + 18 = 90
8a = 72
a = 72/8
a = 9
<span>m∠ZWT = 3a + 5 = 3*9 + 5 = 27 + 5 = 32</span>°
44/9 = 4 remainder 8
so as a mixed number it is 4 and 8/9
35 ?? All I remember is that you have to add the perimeter is the easiest to find
