Answer:
the second one
Step-by-step explanation:
X-the number
20 · x² = 20 · x |divide both sides by 20
x² = x |subtract x from both sides
x² - x = 0
x(x - 1) = 0 ⇔ x =0 or x - 1 = 0
Answer: x = 0 or x = 1
Answer:
9.2
Step-by-step explanation:
Use law of sines
a/sinA = b/sinB
5/sin 31 = b/sin 108
b=9.2

Answer:
Using the pythagoras theorem
Let's say the hypotenuse of the first diagram is b
b²=4²+2²
b²=16+4
b²=20
b=✔(20)
In finding x , b will be the opposite and the x be the hypotenuse
x²=(✔20)²+7²
x²=20 +49
x²=69
x=8.31
