Answer:
m∠ABD = 20°
Step-by-step explanation:
The bisector makes angles ABD and BDC congruent, so ...
7x -1 = 4x +8
3x = 9 . . . . . . add 1-4x to both sides
x = 3
m∠ABD = (7x-1)° = (7·3 -1)°
t + 23 > 1 subtract 23 from both sides
t + 23 - 23 > 1 - 23
t > -22
Answer: C or 2 seconds.
To find the vertex in a standard form equation: (-b/2a,f(-b/2a))
plug it in: -64/2*-32 = 2
12 cm
12x15 (150)
2160/180
= 12 cm
He is incorrect because he multiplied the bases.
