Find three consecutive odd integers whose sum is-213.

Degger [83]

X + x + 2 + x + 4 = -213
3x + 6 = -213
3x = -219
x = -73
-73 + 2 = -71
-73 + 4 = -69
Solution: -73, -71, -69

In the right triangle shown,<br> m<br> V<br> = 60° and UV = 18.<br> 60°<br> How long is UW?

frutty [35]

Answer:

Step-by-step explanation:

There are two case I used, since we are not give diagram, so I assumed that U can be the right angle and also assume that W can be the right angle so, I used both assumption to solve, check attachment

1. Using Trigonometry

Assuming that U is the right angle

Tan θ = opp / adj

Tan 60 = UW / UV

Tan 60 = UW / 18

UW = 18 × Tan60

UW = 18 × √3

UW = 18√3

UW = 31.18 unit

Also, assume that W is right angle

Using trigonometry

Sinθ = opp / hyp

Sin60 = UW / UV

Sin60 = UW / 18

UW = 18 × sin60

UW = 18 × √3/2

UW = 9√3

UW = 15.59 unit

Its t-h
because the sinB = AC/AB (=h) and the cosB= CB/AB but the sinA = CB/AB and the cosA =AC/AB
=> SinB = CosA= t; CosB = sinA=h
=>SinA-CosA = t-h
