Answer:
x = 84/5 = 16.8
Step-by-step explanation:
The angle bisector theorem said that
21/15 = x/12
==> 7/5 = x/12
==> x = 84/5
Answer:
I. AC = 15 cm
II. h = 7.4 cm
Step-by-step explanation:
I. Determination of AC
AB = 9 cm
BC = 12 cm
AC =?
The length AC can be obtained by using pythagoras theory as illustrated below:
AC² = AB² + BC²
AC² = 9² + 12²
AC² = 81 + 144
AC² = 225
Take the square root of both side
AC = √225
AC = 15 cm
II. Determination of the height.
AB = 9 cm
AD = 5.1 cm
BD = h =?
The height of the triangle can be obtained by using pythagoras theory as illustrated below:
AB² = AD² + BD²
9² = 5.1² + h²
81 = 26.01 + h²
Collect like terms
h² = 81 – 26.01
h² = 54.99
Take the square root of
h = √54.99
h = 7.4 cm
65.0
This is because 4 is not a big enough number to round up, so you must round down. When it is 5 and over, you can round up.
Question
Is 5 5/6 bigger then 5 5/10?
Answer:
<h2>
yes</h2>
Step-by-step explanation:
5 : 6 = 0.83
5 : 10 = 0.5
0.83 > 0.5
