Which equation can be used to find the unknown length, b, in this triangle?
Romashka-Z-Leto [24]

The equation for finding the hypotneus of a right triangle is
{a }^{2}  +  {b}^{2}  = c {}^{2}
so we know that 4²+b²=5²
so that would simplify as 16+b=25
so x=25-16
which is 9
so therefore we can conclude that
b = 9inches

WILL GIVE BRAINLIEST (Right angle) Trigonometry <br> please help!
nirvana33 [79]

Answer:

<A = 41.4°

Step-by-step explanation:

Recall, SOH CAH TOA

Reference angle = <A

Hypotenuse length = 8

Adjacent length = 6

Since Hypotenuse and Adjacent are involved, we would apply CAH, which is:

Cos A = Adj/Hyp

Plug in the values

Cos A = 6/8

Cos A = 0.75

A = Cos^{-1}(0.75)

A = 41.4096221° ≈ 41.4° (nearest tenth)
