I really need help with this please

x = 102°

Step-by-step explanation:

Given that 2 of the sides are congruent ( both 3.3 ) then the triangle is isosceles and the base angles are congruent ( both 39 )

The sum of the 3 angles in a triangle = 180° , thus

x = 180 - ( 39 + 39) = 180 - 78 = 102°

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,
