In a right triangle with side lengths of 24 cm and 88 cm, what is the length of the hypotenuse?

91 cm to 2 s.f

Step-by-step explanation:

use Pythagoras = a^2 +b^2 = c^2

substitute: 24^2 + 88^2 = c^2

= 576 + 7744 = c^2

= 8320 =c^2

c = square root of 8320 = 91 to 2 s.f figures

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
