I think your question is missing the key information about the degree of the big angle. So please have a look at the attach photo below, it may help you.
the measure of angle ABD = ∠ABC - ∠DBC
= 109 - 55
= 54 degree
Answer:
Step-by-step explanation:
the formula for calxulating the area if the isosceles triangle is expressed as;
b is the base of the triangle
h is the altitude
Given
b = 16ft
h = 10ft
Substitute
A = 1/2 * 16 * 10
A = 8*10
A = 80ft²
Hence the area of the triangle is 80ft²
b) To get the measure of one side of the triangle, we will use the pythagoras theorem. Let s be the slant side
s² = h²+(b/2)²
s² = 10²+(16/2)²
s² = 10²+(8)²
s² =100+64
s² =164
s = √164
s = 12.8ft
Hence one side of the triangle is 12.8ft
