A. Since a negative times a negative is a positive, (-5)(-9) would be 45.
B. 2 - 4 = -2
C. 12/(-4) = -3
D. Adding a negative is essentialy the same thing as subtracting, so -3 + (-7) is the same thing as -3 - 7, which equals -10.

Therefore, the only equation that results in a positive value is A.

A=42°, b=10, c=12. What is the length of a to the nearest tentH
Digiron [165]

The length of a in the triangle to the nearest tenth is 8.1 units.

<h3>How to find side of a triangle?</h3>

The side a of the triangle can be found using cosine formula.

Therefore,

a²= b² + c² - 2bc cos A

a² = 10² + 12² - 2 × 10 × 12 cos 42°

a² = 100 + 144 - 240cos 42

a² = 244 - 178.354758115

a = √65.6453

a = 8.10217871933

a = 8.1
