Let us find the slopes of the two lines
ax+by=c, slope m1 = -a/b
bx-ay=c, slope m2 = b/a
m1*m2 = (-a/b)(b/a) = -1
Therefore the two lines are perpendicular so the answer is D
Answer:
b= -32b+32
Step-by-step explanation:
You multiply the 8(-b-4) then multiply the b by 4
Answer:
C. 1.12
Step-by-step explanation:
There are 60' (minutes) in a degree and 60" in a minute meaning that we have (60×60) seconds in a degree.
Therefore to convert seconds to degrees we divide by 3600. and minutes to degrees we divide by 60.
The angle 48°19'23'' can be converted into a decimal as follows
48°+(19/60+23/3600)°
=48.323°
Tan 48.323= 1.12
Answer:
Acute Angled Triangle.
Right-Angled Triangle.
Obtuse Angled Triangle
Step-by-step explanation:
a right angle would be 90° angle
obtuse would be over 90°
acute would be smaller than 90°
hope this helps!
