Answer:
segment a = 12
Step-by-step
2 transversal lines will create similar figures. this means that by doing
a/20= 9/15, you can calculate the length of segment a since they will be similar
Answer:
-2/8
Step-by-step explanation:
The rule of additive inverse stays the same with fractions
-12
4=-8-x
Add 8 to each side
12=-x
Divide both side by -1
-12=x
Right Triangles and the Pythagorean Theorem
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).
