Answer:
2 /√3 or 2√3 / 3.
Step-by-step explanation:
Referring to the 30-60-90 triangle: hypotenuse = 2 , smaller leg = 1 and longer leg = √3 and the shorter side is opposite the 30 degree angle.
So cos 30 = √3/2
Sec 30 = 1 / cos 30
= 2 /√3
or 2√3 / 3.
Answer:
the answer is 25
Step-by-step explanation:
because (4x-25) is equal to 75
so put the equation together and solve for x
4x-25=75
+25= 75+25
4x=100
x=25
