bixtya [17]

from the given equation

X+Y=20-->i

X-Y=14--->ii

add eq i and eq ii

2x=34

x=17

putting the value of x=17 in eq i

17+y=20

then y = 3 so the right answer is

17 and 3

Find the angle measure. It is not asking for X

MrMuchimi

<h3>Answer: 131 degrees</h3>

Work Shown:

(angle JIW) + (angle WIH) = angle JIH

(2x+8) + (101) = 11x + 10

2x+109 = 11x+10

2x-11x = 10-109

-9x = -99

x = -99/(-9)

x = 11

So,

angle JIW = 2x+8 = 2*11+8 = 22+8 = 30 degrees
angle WIH = 101 degrees
angle JIH = 11x+10 = 11*11+10 = 121+10 = 131 degrees

The smaller angles add to 30+101 = 131 to confirm we have the correct answer.
