Question

Pythagorean Theorem with an Unknown Leg

Answer 1

Answer:

b = √45

Step-by-step explanation:

As mentioned in the picture :

a² + b² = c²

a=2 , c = 7 (as it is opposite the right angle)

Now we substitute these values :

2² + b² = 7²

4 + b² = 49

Subtract 4 from both sides :

b² = 45

Square root both sides :

b = √45

Hope this helped and have a good day

Answer 2

Answer:

It's got to be either 45 or 6.7

pretty sure that it's 45

Step-by-step explanation:

algorithm: a^2 + b^2 = c^2

substitute: 2^2 + b^2 = 7^2

4+ b^2 =49

4-4 + b^2 = 49-4

49-4=45

b^2=45

Please give me brainliest if this is correct!!!!!

Have a great day and God bless!!!!
