In ΔGHI, the measure of ∠I=90°, the measure of ∠G=21°, and GH = 31 feet. Find the length of IG to the nearest tenth of a foot. please help

28.9

Step-by-step explanation:

cosG=

hypotenuse

adjacent

=

31

x

\cos 21=\frac{x}{31}

cos21=

31

x

31\cos 21=x

31cos21=x

x=28.941\approx \mathbf{28.9}\text{ feet}

x=28.941≈28.9 feet

its adding 5.5 each time

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
