Question

the height of a right angle triangle is 7 cm less than its base if the length of its hypotenuse is 13 cm find its hight and measure of base​

Answer 1

Answer:

Hey mate

You will do this by Pythagoras theorem

AC is hypotenuse = 13 cm

AB is height =7cm

BC is base =?

AC²=AB²+BC²

13²=7²+BC²

169=49 +BC²

BC²= 169-49

BC²=120

$bc = \sqrt{120}$

$= \sqrt{4 \times 30}$

$= 2 \sqrt{30}$

BC=2√30
