104-32=72 brownies
72/32= 2.25
Ratio: 1 cookie:2.25 brownies
A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
Answer: -4.5
Step-by-step explanation:
Just took the quiz
Answer:
X = 40 degree
Step-by-step explanation:
First I would name the points whatever you do always name the points it really helps
So,
75 = a
50 = b
The middle point will be o
85 = c
X = d
Ok so,
Angle aob = y
Angle cod = z
Now,
75+50+y=180 (angle sum property)
y=180-125
y=55
Angle y = z (vertically opposite angles)
55+85+x=180 ( angle sum property )
x=180-140
Therefore x=40 degree
In higher classes you will be able to do this in your mind itself without calculation all you need is practice.
