Question

What’s the answer for this? :)

Answer 1

Answer:

13

Step-by-step explanation:

2x-5=21    (we know this because it is an iscoleces triangle)

2x=26

x=13

Answer 2

Well I’m not sure why the answer isn’t in the multiple choice

First solve the triangle
24-10= 14
The hypotenuse is 21, so 21 squared minus 14 squared and the square root the answer which is 14

On the other triangle we know that 10 squared plus 14 squared is the hypotenuses. This gives us 17.205
Then use the equation to find x
2x - 5 = 17.205
2x = 22.205
X = 11.1025

Man I hope this is right
