Question

Please please please help me.

Answer 1

Answer: sorry i just know no.2

Explanation:

2) = soln

h = ?

p = 5

b =9

`h^2 = p^2 + b^2\\h^2 = 3^2 + 9^2\\or, h^2 = 9+81\\or, h^2 = 90\\so, h = √(90) \\\\`

Let the angle be x

so

tan x = p/b

tan x = 5/9

x =
`tan^(-1) (5/9)`

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°
