Answer:
See below
Step-by-step explanation:
<u>Given points:</u>
- A (3, -1)
, B (9, 2)
, C (6, -4)
First, plot the points on the coordinate plane (see attached)
<u>We see that AB and BC look the same. Let's find their length:</u>
- AB =
- BC =
We showed that AB = BC = 3√5, so the triangle has two sided of the same length, therefore is isosceles.
Is these 41/2,2/3,1/4,1/2,21/3 The first thing, calculate m.c.m of these denominator
2=2
3=3
4=2.2
12
246/12,8/12,3/12,3/12,6/12,84/12, In order is like this
246/12,84/12,8/12,6/12,3/12
41/2>21/3>2/3>1/2>1/4 0r
1/4<1/2<2/3<21/3<41/2
Using Pythagoras theorem :
C = sqrt(a^2 + b^2)
C = sqrt(36+64)
C = sqrt(100)
C = 10 feet
The number is 157, because it's 100-200, 10-5=5 (ones place) & 5+2=7 (tenths place)
