Answer:
2.33 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = AC / BC
tan 25 = AC / 5
Multiply each side by 5
5 tan 25 = BC
2.331538291 = BC
To the nearest hundredth
2.33 = BC
The answer is the last one y=2.60z+180
The function f(x) = -5x^2+ 3x + 4 has a maximum.
2x-2+x+5=90
3x+3=90
-3 -3
3x/3 =87/3
x=29
