STR is a triangle as shown in the picture. If Luke decided to subtract 128º from 180º, that's because he understood that the sum of the internal angles in a triangle is 180º, and therefore the angles RST and TRS together make 128º.
As a result, RST will be
128º - TRS
where TRS is the angle at R, as shown in the picture
The answer is:
A. 10
This is because segment AB is parallel to segment DC, meaning they are the same length.
Hope this helps!
D.). I think. yeah because 2 side are equal and 1 isn't.
Answer:
Slope of parallel: -1/4
Slope of perpendicular: 4
y=mx+b
m=slope
parallel= slope
perpendicular= slope opposite
Answer: 1.2
Step-by-step explanation:
Let X denotes the grades on a language midterm at Oak Academy.
As per given ,
X follows normal distribution ( because it has symmetric graph)
Formula for z : 
For X = 70, we have
Hence, the z-score for Ishaan's exam grade = 1.2
