Work out the lengths of side a and side b 8cm and 5 cm 1 triangle 17cm and 12 cm on the other triangle pythagoras
Viktor [21]

Answer:

a = 9.4 cm

b = 12.0 cm

Step-by-step explanation:

Check the image uploaded for diagram;

For the first diagram, side length a is calculated as follows;

a² = 8²  +  5²

a² = 64  +  25

a² = 89

a = √89

a = 9.4 cm ( approximated to 1 decimal place)

For the second diagram, side length b is calculated as follows;

b² = 17²  -  12²

b² = 145

b = √145

b = 12.0 cm (approximated to 1 decimal place)

Write the coordinate of A' after A (5.3) got reflected over the x-axis.​
Lana71 [14]

Answer:

(-5,3)

Step-by-step explanation:

When you reflect over the x axis the numbers will be the same but the sign will change depending on which quadrant you end up in.

(5,3) will reflect over x axis and become (-5,3) and will be in the 2nd quadrant after reflecting.
