Answer:
B(4, - 3 )
Step-by-step explanation:
We have A(2, - 7) and C(7, 3 )
Using the section formula to calculate the coordinates of B
= 
= 
= 
= 4
= 
= 
= 
= - 3
Hence B(4, - 3 )
Answer: 170
Step-by-step explanation:
The formula for the area of a triangle is 1/2bh, where b is the base length, and h is the height.
So- Essentially you’d just need to plug in the variables to solve this. the semicircle on the bottom serves to tell you the base length.
1/2(20)(17)
170
The lower square root would be 4.2
You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.
b= square-root of (c^2)-(a^2)
b= square-root of (9^2)-(2^2)
b= 8.77.... which in the exact form is square root of 77.
