Problem 10
<h3>Answer: 80 degrees</h3>
Work Shown: 80-0 = 80
You subtract the values on the protractor where the two angle arms line up.
============================================
Problem 11
<h3>Answer: 45 degrees</h3>
Work Shown: 45-0 = 45
Same idea as problem 10
============================================
Problem 12
<h3>Answer: 83 degrees</h3>
Work Shown: 128-45 = 83
Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.
============================================
Problem 13
<h3>Answer: 35 degrees</h3>
Explanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.
Answer: Dist = 8.94, midpoint = (1,6)
Step-by-step explanation:
Basically, the Distance between the points is the hypotenuse of a right triangle, whose legs are parallel to the x and y axes.
Leg 1 = x2 - x1 = 5 - -3 = 8
Leg 2 = y2 - y1 = 8-4 = 4
Hypotenuse = (8^2 + 4 ^2) ^ .5 = (64+16)^.5
Sqrt(80) = 8.94
The midpoint is aligned with the midpoint of each leg
X = 5 - 8/2 = 1
Y = 8 - 4/2 = 6
So (1,6) is the midpoint
BC= 85 think u cam try or try this 51
Answer:
= -x+6
Step-by-step explanation:
we can simply substitute (x-4) in x place because when we say function of x , we are basically saying when we substitute a given value in the place of x we will find a given y.so for example if we have a question f(4), we can simply plug 4 to -x +2 so we will find y or f(x) = -2.
so the answer for the above question will be f(x)= -x +6.
