Answer: 35
Step-by-step explanation:
Triangle BDC is an equilateral triangle
Triangle ABD is an isosceles triangle
so the length of BD is 8
because BDC is equilateral all sides are 8
then you add your numbers up
8+8+8+11
=35
Answer:
25
Step-by-step explanation:
GC and BD are 2 intersecting chords thus the measure of the angle formed is
∠DFC = 0.5( m arc CD + m arc BG ), that is
0.5(55 + BG) = 40 ( multiply both sides by 2 )
55 + BG = 80 ( subtract 55 from both sides )
BG = 25
Answer:
69
Step-by-step explanation:
to find f(3), we'll have to substitute x with 3
therefore,
f(3) = 19 × 3 + 12
= 57 + 12
= 69
