What angle are we trying to find?? show the question
Answer:
option 2.
m1 = 147° m2 = 80° m3 = 148°
Step-by-step explanation:
a flat angle has 180 °
m1 + 33 = 180
m1 = 180 - 33
m1 = 147
47 + 33 + x = 180
x = 180 - 47 - 33
x = 100
as they are two crossed lines the angle is reflected from the opposite side
48 + 100 + y = 180
y = 180 -100 - 48
y = 32°
180 = m3 + 32
m3 = 180 - 32
m3 = 148
With the same principle as the previous one we know that the angle of a turn is 360 °, if we subtract the 2 known angles and divide it by 2 we will obtain the missing angle
m2 * 2 = 360 - 100*2
m2 = 160 / 2
m2 = 80
Answer:
260 gallons
Step-by-step explanation:
An estimate of 26.5% of the water used each day is for cleaning and a family uses 68.9 gallons of water a day for cleaning,
Percentage of water used for cleaning= 26.5%
Gallons of water used for cleaning= 68.9
Let the number of gallons used everyday be represented by g. This will give:
26.5% of g = 68.9
26.5/100 × g = 68.9
0.265 × g = 68.9
0.265g = 68.9
Divide both side by 0.265
0.265g/0.265 = 68.9/0.265
g= 260
260 gallons of water are used everyday
For the midpoint, you find the differences in x values and y values then divide them by 2. Like so:
Let's do x first:
(-16-0)/2 = (-16)/2 = -8
So our x coordinate is -8.
Now Y:
(-16)/2 = -8
So our Y coordinate is -8 as well.
So your answer is:
(-8,-8)
A=3/7 b=4....................
