Question

It’s about right triangles but it’s confusing

Answer 1

Answer:

Its D

Step-by-step explanation:

Imagine that we have a 2 cm straw that will be the height.

5 cm is for the base

So the upper one must longer than the base

So its 7 cm

Answer 2

Answer:

A

Step-by-step explanation:

Use Pythagorean Theorem, which is for side lengths of right triangles.

a^2 + b^2 = c^2  (c is the hypotenuse)

Common combination is 3-4-5. Just by looking at the answers, I can see A is 3-4-5 except everything is multiplied by 2.

B is wrong. It would be 5-12-13 if it were a RT.

C is wrong. 3-4-5

D is wrong. 4 + 25 = 49 is not an equation.
