Find GH.<br> picture is attached
Ede4ka [16]

Answer: 4.6

Step-by-step explanation:

GH is equal to 4.6 since it is congruent to JH. GJ is one line, which makes angles GKH and JKH supplementary angles. Since angle GKH = 90, angle JKH must also equal 90, making these triangles similar. However, if you wish to see it done out mathematically, the following explanation is there:

a^{2} + b^{2} = c^{2}

3.6^2 + HK^2 = 4.6^2

HK^2 = 4.6^2 - 3.6^2

HK^2 = 8.2

HK = 2.86

HK^2 + GK^2 = GH^2

8.2 + 12.96 = GH^2

GH = 4.6

Choose all of the points that would be on a graph for y=7x
pav-90 [236]
Hey there! :D

Plug in the points to see if they work. 

y=7x

(2,14) -> (x,y)

14=7*2

14=14

That works. 

(0,0) 

0=7*0

0=0

That works 

(1,7)

7=7*1

7=7

That works. 

The points that work are (2,14), (0,0), and (1,7)

I hope this helps!
