Answer: sorry i just know no.2
Step-by-step explanation:
2) = soln
h = ?
p = 5
b =9
[tex]h^2 = p^2 + b^2\\h^2 = 3^2 + 9^2\\or, h^2 = 9+81\\or, h^2 = 90\\so, h = \sqrt{90} \\\\[/tex]
Let the angle be x
so
tan x = p/b
tan x = 5/9
x = [tex]tan^{-1} (5/9)[/tex]
so, x = 29.054
rounding off to ten
x = 29.1
now
let the another angle be y
so
90+y+29.1 = 180
29.1 + y = 180-90
y = 90-29.1
so, y = 60.9
the missing side is √90 and missing angles are 29.1° and 60.9°
