Question

hello good morning answer this question

a rectangle has a side of 15m and diagnols 27m. find the angle between the longer side and the diognal​

Answer 1

Answer:

(sin)^-1  X 5/9

Step-by-step explanation:

l = 15 m

diagonal = 27 m

consider the triangle formed by diagonal , length and breath of rectangle

by pythagoras theorem 15^2 + b^2 = 27^2

b^2 = 576-225 = 351

b = 18.73

so 18.73 is longer side

     

x= angle between longer side and diagonal

sin x = 15/ 27 = 5/9

x = (sin)^-1  X 5/9
