Find how long will he take for 1 similar walls (in hour)
1/3 × 3/4
= 3/12
= 1/4 hours
Find how long will he take for 5 similar walls
time for 1 wall × 5
= 1/4 × 5
= 5/4 hours
M=-1/2 is the slope
x+2y=6
2y=-x+6
y=-1/2x+6
y=mx+b
m is slope
Answer:
x + y = 90 - - - (1)
y = 1/4x - - - - (2)
Step-by-step explanation:
x = larger acute angle
y = smaller acute angle
Recall:
A right angle measures 90°
Sum of angles in a triangle = 180°
y = 1/4x
Hence :
90 + x + y = 180
x + y = 180 - 90
x + y = 90 - - - (1)
y = 1/4x - - - - (2)
Put y = 1/4x in (1)
x + 1/4x = 90
1.25x = 90
x = 90 / 1.25
x = 72
x + y = 90
72 + y = 90
y = 90 - 72
y = 18
