Tan² B = 4
(tan B)² = 4
tan B = ±2
Basic Angle
= tan^-1 2
= 63.4° (1dp)
B = 63.4°, 116.6°, 243.2°, 296.6°
Assuming you're actually supposed to present your answers in 0dp, then all answers apply.
Answer:
y= -10/89
Step-by-step explanation:
89y=-10
89y/89 = -10/89
y= - 10/89
This looks one hundred percent correct to me and to check your answer you can plug in the answer you find to the first equation
17=37+4f
17=37+4(-5)
17=37-20
17=17
great job!!
The correct answer is D
since 3.2222... is a repeating number, it is rational
0.112123123412345 is not repeating and doesn't have a cosistent pattern, so it isn't rational
1.589 is rational because this decimal stops and doesn't continue- it can also be written as a fraction ( 
)
">" means results into or you can think about it as saying equals (=)
√75 = √5 * √15 > √5 * √5 * √3 > 5<span>√3
</span><span>√3
</span>√75 = √5 * √15 > √5 * √5 * √3 > 5√3
√3
Which then leads to..
5√3 + 5√3 + √3 + √3
