The answer in slope-intercept form is y= -3/4x+2
60,000 ton a year is correct
Answer:
1)
Angle 1: 59
Angle 2: 88
Angle 3: 147
2)x =21
Step-by-step explanation:
1)
Angle on a straight line add up to 180 degrees and angles in a triangle add to 180 degrees
2)
Opposite angles are equal. (4x) and (2x+42) are opposite therefore equal, so
4x=2x+42
Minus 2x from both sides
2x = 42
Find 1x by dividing 42 by 2, therefore
X=21
Answer:
See below.
Step-by-step explanation:
Use the compound angle identity:
sin(A - B) = sinA cosB - cos A sin B.
Plugging in the given angles:
A = 360 and B = O so:
sin (360 - O) = sin 360 cos O - cos 360 sin O
sin 360 = 0 and cos 360 = 1 therefore we have
0 * cos O - 1 * sin O
= 0 - sin O
= -sin O.
