Answer: B 11/15
Step-by-step explanation: 11/15 = 22/30> 20/30
but 11/15 = 110 /150 < 120/150 = 30/50
Answer:
D) 20°
Step-by-step explanation:
Using the triangle sum theorem, you know that every triangle's interior angles add up to 180°. Therefore the bottom triangle's missing angle can be found by giving it the variable x.
57° + 30° + x = 180°
Simplify: 87° + x =180°
x=93°
By the vertical angles theorem, the vertical angle directly across this angle is congruent to this one. Meaning that the top triangle's angle are 67°, 93°, and unknown, which we can assign y. We can use the same method from above here.
67° + 93° + y = 180°
Simplify: 160° + y = 180°
y=20°
Answer:
21/40
Step-by-step explanation:
X2+16 is the prime <span>polynomial.
x2+16 is the only </span><span>polynomial that couldn't be factored out anymore
x2-36 --> (x-6)(x+6)
x2-7x+12 --> (x-3)(x-4)
x2-x-20 --> (x+5)(x-4)</span>
