Answer:

x = 2 y= -1/2

Step-by-step explanation:

5x-2y=11 {1} . 2

3x+4y=4 {2} . 1

-> 10x-4y=22

+ 3x+4y = 4

-> 13x = 26

-> x= 26/13 x= 2/1 x= 2

-> 3(2)+4y=4

->6+4y=4 -> 4y= 4-6

-> 4y= -2 -> y= -2/4 -> y=-1/2

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.

Vilka [71]

Answer:

$IG=28.9\ ft$

Step-by-step explanation:

we know that

In the right triangle GHI

$cos(G)=\frac{IG}{GH}$ ----> by CAH )adjacent side divided by the hypotenuse)

substitute the given values

$cos(21^o)=\frac{IG}{31}$

solve for IG

$IG=cos(21^o)(31)=28.9\ ft$

see the attached figure to better understand the problem
