Answer:
angle R
Step-by-step explanation:
To solve this we will use cosine rule
Cosine rule
cos(A) = 
suppose,
q = 6.25
s = 11.04
r = 13.19
angleQ = 
= 30.58
angleR = 
= 93.82
angleS = 
= 56.63
Answer:
Relation 1 : Not a function
R2 : Function
R3: Function
R4: Not a function
Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
Answer:
x = 30 I'm sure hope this helps
