Answer:
1863 
Step-by-step explanation:
( 23 x 12 ) x 2 = 552
69 x 19 = 1311
1311
<u>+552</u>
= 1863

Step-by-step explanation:
I believe the answer is segment FD
Answer:
The value of rate of which the base is changing
= - 3 
Step-by-step explanation:
Area = 20 
height = 4 cm


we know that area of the triangle is given by



B = 10 cm
Rate of change of area is given by
![\frac{dA}{dT} = \frac{1}{2} [B\frac{dH}{dt} + H \frac{dB}{dt} ]](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7BdT%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5BB%5Cfrac%7BdH%7D%7Bdt%7D%20%2B%20H%20%5Cfrac%7BdB%7D%7Bdt%7D%20%5D)
4 = 0.5 [10 × 2 + 4
]
= - 3 
This is the value of rate of which the base is changing.
Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.

They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if

, the triangle is right
- if

, the triangle is acute
- if

, the triangle is obtuse

The triangle is obtuse.
The answer is D.
