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
1 answer:
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)

2) y= 2x+4
Step-by-step explanation:
For number one, use the formula .
Insert the given coordinates into the formula.
7-1/10-1= 6/9
Simplify 6/9.
6/9÷3= 2/3
For the second one, I used desmos calculator.
Hope this helps! :)
