Answer: The probability is 3 out of 20
Step-by-step explanation:
Answer: it is not a function if the x repeats
Step-by-step explanation: My teacher always says THE X DOES NOT REPEAT that is the easiest way to remember it
Answer:
x=2√5
Step-by-step explanation:
<u>1st method:</u>
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
<u>2nd method:</u>
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
<u>3rd method:</u>
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5
15x, because 2 × 4x= 8x and -1×-7=7x...add 8x and 7x ull get the answer
