Answer:
yes
Step-by-step explanation:
1. GCF is 7 so answer is 7(5+6)
2. GCF is 5 so answer is 5(3+8)
The sum of two irrational numbers is only sometimes rational... So the answer is D.
Answer:
A) 0.9(sin50)
Step-by-step explanation:
Since this is a right triangle, we can use
sin a = opposite side/ hypotenuse
sin 50 = x /.9
Multiply each side by .9
.9 * sin 50 = x/.9 * .9
.9 (sin 50) = x
