Answer:

Step-by-step explanation:
Suppose we have a triangle WXY whose internal angles are:



The sum of the measures of the angles must be 180°, thus:

Simplifying:
15x + 15 = 180
Subtracting 15:
15x = 165
Dividing by 15:
x = 11
Thus, the measure of angle Y is


Answer:It would be -4 across and go two up
Step-by-step explanation:
I think you forgot to put the image in the question
<u>Answer:</u>
The coordinates of endpoint V is (7,-27)
<u>Solution:</u>
Given that the midpoint of line segment UV is (5,-11) And U is (3,5).
To find the coordinates of V.
The formula for mid-point of a line segment is as follows,
Midpoint of UV is
, 
As per the formula,
=5,
=-11
Here 
Substituting the value of
we get,
=5



Substituting the value of
we get,
=-11



So, the coordinates of V is (7,-27)
Answer:
13.7 cm
Step-by-step explanation:
- there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
- since we know that 360°-260.4°=99.6°
- The angle measure of arc AD is 99.6°
Now that we covered that, we can use the arc length formula in order to find the length of arc AD.
- arc length = 2πr(Θ/360°)
- 2π(7.9)(99.6°/360°) = 13.7329
- rounded to the nearest tenth = 13.7
