Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
Answer:
A. 8
Step-by-step explanation:
6.0061 x 10^7
/ = 6/8 x 10^7/10^6
7.8483 x 10^6
0.75 x 10^7-6
0.75 x 10^1
A: 0.75 = 7.5 = 8.
