Step-by-step explanation:
given,
measures of 3 angles of triangle,
angle 1 = 3x
angle 2 = 2x + 15°
angle 3 = 3x + 5 °
sum of the angles should be 180°
so,
angle 1 + 2 + 3 = 180°
after inserting the values we got,
3x + 2x + 15 + 3x + 5 = 180°
→ 8x + 20 = 180°
→ 8x = 180 - 20 = 160°
→ x = 160/8 = 2
→ x = 20
therefore,
angle
1 = 3x = 3 × 20 = 60
2 = 2x + 15 = 2(20) + 15 = 55°
3 = 3x + 5 = 3(20) + 5 = 65°
as given,
their sum should be 180° so,
60 + 55 + 65 = 180°

Answer:
D.a relation only
Step-by-step explanation:
Relation: It is mapping between two non empty set A and B.
In relation any input value can have two or more than two output values.
Function: It is that relation in which every input value has only one output .
All function are relations but all relations are not function.
In given data
Image of 3 =4
Image of 3=3
By definition of function
It is not a function.
By definition of relation
It is a relation.
Hence, option D is true.
