Answer:
Angle SRT is equal to 79 degrees
Step-by-step explanation:
The reason this is so is because for every single triangle all the angles must add up to 180 degrees. So take 180 minus angle T, and then minus angle S and you get 79.

Answer:
3. a line perpendicular to a given line through a point not on the line
Step-by-step explanation:
The point not on the line suggests that choices 1 and 3 are possibilities. The fact that the dotted line is not parallel (and is perpendicular) to the solid line suggests that choice 3 is applicable and choice 1 is not.
The short arcs are equidistant from the end points of the chord that intercepts the larger arc. Hence the line through the crossing point of the short arcs and the point on the other side of the line will be the perpendicular bisector of the chord, and will be perpendicular to the solid line. Creating that perpendicular is likely the purpose of the construction.
Answer:
2
Step-by-step explanation:
Given:
Total length of ribbon = 1 yard
Length of ribbon used for project = 
yard
Length of ribbon the rest of ribbon is to be divided = 
yard
To find:
The number of ribbons of length yard that can be made = ?
Solution:
Length of ribbon left after the 1 yard ribbon is used for project can be calculated by subtracting the length of ribbon used from the initial length of ribbon.
i.e.
Length of ribbon left = 
yard
Now, number of ribbon of length yard can be found be dividing the length of ribbon left with the length of ribbon pieces to be cut.
i.e.
Number of ribbons:
