Answer:
Angle R is 99 degree
Angle Y=48 degrees
Angle T is 33 degrees
Step-by-step explanation:
Let angle T be x
Angle R will be 3x
Angle Y will be x+15
Total=x+3x+x+15=5x+15
5x+15=180
5x=165
x=165/5=33
Therefore, angle T is 33 degrees, angle Y=15+33=48 degrees and angle R=33*3=99 degrees
Answer:
c
Step-by-step explanation:
Looking at the image of the cube you can see the outer edges would have paint on 2 sides and the corners would have paint on n3 sides.
The only ones with paint on one pace is the center cubes.
