Question

Geometry !! Please help I missed the lesson because of a funeral!!!

Answer 1

let's do the first three there, tis just a matter of using the pythagorean theorem, and the others are more or less the same thing, check the picture below.

Answer 2

Use the Pythagorean Theorem which is a^2+b^2=c^2
For example, on number 1

Step 1: Substitute
19^2+16^2=c^2
Step 2: Square the numbers
361+256=c^2
Step 3: Add
617=c^2
Step 4: Get the square root of both sides to isolate c
sqrt(617)=c

Answer
24.8=c

x is c btw
