Answer:
12
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
use you law of sine
missing angle A = 41
21/sin41=x/sin24 = 13
21/sin41=x/sin115 = 29
Answer:
x = 3
Step-by-step explanation:
take 60 degree as reference angle and using cos rule
cos 60 = adjacent/hypotenuse
1/2 = x/6
do cross multiplication
2*x = 6*1
x = 6/2
x = 3
The difference between an algebraic expression and a numerical expression is that algebraic expressions contain numbers and variables. Numerical expressions only contain numbers.
Ex:
Algebraic Expression- 5x+9
Numerical Expression- 4+2
