Answer:
the 3rd one
Step-by-step explanation:
Answer:
C. 120°
Step-by-step explanation:
Let angle A be x, then angle C is 2x
The sum of the angles in ABC is
A + B+ C = 180
x+90 +2x = 180
3x +90 = 180
3x= 90
Divide by 3
x = 90/3
x = 30
Angle A = 30, Angle C = 2x = 60
AH = BH, so it is an isosceles triangle . That means A and ABH are equal
A = 30 , ABH = 30
The sum of the angles in ABH must equal 180
A + ABH + BHA = 180
30 + 30 + BHA = 180
60 + BHA = 180
BHA = 180-60
BHA = 120
B. Is correct
Y= -450x + 18,000 or in other words y= 18,000 - 450x
