Answer:
The middle number would be (14+15)/2 = 14.5
How I found that is I did (14+15)/2.
pls mark as branliest
I think the answer would be like 1.5.
Answer:
Y=70
X= 20
You do first the adjacent angles 180-40 so 140 then u have that the triangle is isosceles so the bas angles are equal 180 -140 = 40
40 divided by 2 20 and 20 so x= 20
Then 90 -20 is 70
So 180 - (70+40)
180-110=70 so y= 70
Hope you understand
7.5cm
lets take point K represent lenght from M to perimeter of circle.
r is radius
KM= r-OM= r-4.5cm
now lets draw line from O to A (OA)
we get triangle.
hypotenuse is OA and it equals r(radius)
ab=12 cm. so another side of the triangle (AM) is 12/2=6cm. and the last side of the triangle is 4.5(OM)
use pythaghorean theorem
squares of sides added = square of hypotenuse
20.25+36=r^2(our hypotenuse is radius)
56.25=r^2
r=√56.25=7.5cm
Answer: 89:100
Step-by-step explanation:
89% out of a possible 100%
So, ratio will be 89:100
