Answer:
a)
AB = 3(sq rt 48) - 5(sq rt 12) + sq rt3
AB = 3(sq rt 16x3) - 5(sq rt 4x3) + sq rt3
AB = 12(sq rt 3) - 10(sq rt 3) + sq rt3
AB = 3(sq rt 3)
b)
AC = (3 - sq rt 6)(3 + sq rt 6)
AC = 9 + 3(sq rt 6) - 3(sq rt 6) -6
AC = 9 - 6
AC = 3
BC = (3 - sq rt 5)^2 + 2(3sq rt 5-4)
BC = 9 - 6sq rt 5m + 5 + 6sq rt 5 - 8
BC = 9 + 5 - 8 = 6
BC = 6
c)
If right triangle, AB^2 + AC^2 = BC^2
(3sq rt 3)^2 + 3^2 = 6^2
27 + 9 = 36
36 = 36
Answer:9
Step-by-step explanation:
1st triangle is similar to the second one as the angles of both of the triangles are the same..
So we know the ratio of the similar lines will be constant.it means,
XY/PQ=XZ/PR=YZ/QR
So,Xy/PQ=XZ/PR
21/7=27/x
X=(27×7)/21
X=9
Thats the value of pr..

The answer is A. 40.8
since the problem gave you the diameter all you have to do is multiply the diameter by pi (3.14) to get the circumference.
Extra Help:
If a similar problem gives you only the radius (half the diameter) then you multiply the radius by 2 to give you the full diameter. Once you get that answer you just need to multiply the diameter by pi (3.14) to get the circumference.
A triangle can only have one hypotenuse. The other sides are called legs.
The hypotenuse is the longest side of a triangle.
