If m∠FBC = (10x –9)°, m∠CBE = (4x + 15) °, find m∠FBE

(14x+6)°

Step-by-step explanation:

Given  m∠FBC = (10x –9)° and m∠CBE = (4x + 15), the following expression will be used to find m∠FBE

m∠FBE = m∠FBC+m∠BE

Substituting the given functions

m∠FBE = 10x-9 + 4x+15

collect like terms

m∠FBE = 10x+4x-9+15

m∠FBE = 14x + 6

Hence m∠FBE is (14x+6)°

1/4 because there is 4 grades.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
