What is the missing leg length of the hypotenuse 23 and the other leg is 11??
valentinak56 [21]
To find the 3rd side of a triangle, use the pythagorean theorem.
a^2 + b^2 = c^2

a = 11
b = ?
c = 23

11^2 + b^2 = 23^2
121 + b^2 = 529
b^2 = 408
b = √408 = 2 √102 = 20.199, 20.2, or 20

The answer can be any of those.

Will someone please explain this to me?​
Elza [17]

Step-by-step explanation:

m<DAC is the exterior angle of the right angle triangle, where m<ACB and m<ABC are the interior angles of the triangle opposite to the exterior angle

Sum of the opposite interior angles is equal to the exterior angle

m<ACB+ m<ABC=m<DAC

a°+90°= 119°

a°=119-90°

a°=29°
