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:
Total Cost = $1.47
Step-by-step explanation:
Length of the wooden board = 
Cost of the wooden board = $0.25 per foot
Total Cost = Cost per foot X Total Length in foot
= 
Total Cost = $1.47
54.7 cm because a squared + b squared = c squared
Answer:
y= 2x -3
Step-by-step explanation:
The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, this is your current equation: y= 2x + b. Next, substitute your point into the equation to get the y-intercept. It should look like this: 9=2(6) + b. 6 times 2 equals 12. Now, this is what it should look like: 9=12 + b. Subtract 12 from both sides to get -3 = b. Go back to your original equation and plug in -3 to b. This is your final equation: y= 2x -3. Hope this helped!

Step-by-step explanation:
According to the graph, we see that both lines intersect at <em>x</em> = 3. Therefore, that means both lines at that <em>x</em> point will have the same <em>y</em> value. Both f(3) and g(3) would equal 6, leading us to the answer of f(3) = g(3).
