Step-by-step explanation:
Note that since 
we can see from the figure that 
and 
have the same measure.
a) To solve for the length of 
we write
b) Since the two triangles are congruent, we can say that 
so we can write
Solving for y, we get
49, here's why...
a negative multiplied by a negative equals a positive, and if you're working with parentheses, and you don't see a sign, at all, then it means you have to multiply.
hope I helped :)
It has to be this simple right? 18 holders thirty candles. but if only one candle fits in each holder then there is only 18 decorations possible
Answer:
x = ±1/2
Step-by-step explanation:
x^2-1/4=0
Add 1/4 to each side
x^2 -1/4+1/4 = 0+1/4
x^2 = 1/4
Take the square root of each side
sqrt(x^2) = sqrt(1/4)
x = ±1/2
Hey,
So the slope formula is (y2-y1) over (x2-x1). Then plug in your numbers. If needed, simplify the slope. You’ll noticed that the answer is undefined. Work is attached. Hope that helps!
