Find the missing side using the pythagorean theorem

____ [38]

Answer:

26.55

Step-by-step explanation:

$a^2 + b^2 = c^2\\b^2 = c^2 - a^2$

use the b^2 equation

------------------------

b^2 = 31 squared - 16 squared.

b^2 = 705

b= $\sqrt{705}$

b=26.5518361

Sin x =<br>cos x =<br>tan x =

madreJ [45]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

so Sin(x) = d/f

Cos(x) = e/f

Tan(x) = d/e

got it? :)

PLEASE HELP I DONT UNDERSTAND!!

First set both equations equal to y

y = -1/2x + 3

y = 3x - 4

Then set these two equal because they both equal y

-1/2x + 3 = 3x + 4

Combine like terms and solve

7 = 3.5x

x = 2

y also = 2 when you plug it back in

Therefore, (2,2)
