You're incorrect. an angle of 155 degrees is an obtuse angle. the angle is obviously an acute angle, as it is under 90 degrees. the answer is 50 degrees, or A.
Answer:
A proportion is an equality of two ratios.
...
Things to remember
Determine whether the ratio is part to part or part to whole.
Calculate the parts and the whole if needed.
Plug values into the ratio.
Simplify the ratio if needed. Integer-to-integer ratios are preferred.
Answer:
y = (-5/3)x - 4
Explanation:
The equation of a line with slope m that goes through the point (x1, y1) is:

Additionally, two lines are parallel if they have the same slope.
The slope of the line y = (-5/3)x - 2 is (-5/3) because it is the number beside x.
So, the slope of our line is also -5/3.
Therefore, replacing m by -5/3 and (x1, y1) by (-3, 1), we get that the equation of the line is:

Finally, solving for y, we get:

So, the answer is:
y = (-5/3)x - 4
Answer:
70.8 to one decimal place,
or to be exact : 70.7873
Step-by-step explanation:
In right angle triangles, trigonometry functions can be used
here tan out of sin, cos ,tan seems the most appropriate
tan(x) = opposite/adjacent
tan(x) = 6.6/2.3
x = tan^-1 (6.6/2.3)
x = 70.7873
<span>d. It does, the points shown on the line would be part of y = −2x.
is the answer let me know if this helped</span>
