Answer:
79°c - (-3°c) = 82°c
Step-by-step explanation:
this is because we need to calculate the total gap between those numbers through number line. I have attached the photo, have a look over there.

Step-by-step explanation:
Using the section formula, if a point (x,y) divides the line joining the points (x
1
,y
1
) and (x
2
,y
2
) in the ratio m:n, then
(x,y)=(
m+n

The vertices of the triangle are given to be (x

,y
1
),(x
2
,y
2
) and (x
3
,y

). Let these vertices be A,B and C respectively.
Then the coordinates of the point P that divides AB in l:k will be

Based on the lengths of the given triangles and the length of segment BD, the length of segment AD is 22.20.
<h3>What is the length of segment AD?</h3>
The triangle ABC is a right angled triangle with segment AB being the hypothenuse.
We can therefore find this length using the Pythagoras Rule:
Hypothenuse ² = a² + b²
Hypothenuse ² = 28.6² + 23.2²
Hypothenuse ² = 1,356.20
Hypothenuse = √1,356.20
= 36.83
Length of AD:
= AB - BD
= 36.83 - 14.60
= 22.2
