Answer:

x = -6

y= 1

Step-by-step explanation:

make one of the variables equal to each other

4(2x+3y) = -9

3(-x+4y) = 10

subtract

8x+12y = -36

- -3x+12y =30

----------------------

11x = -66

x = -6

plug back in to find y

8(-6)+12y = -36

12y= 12

y = 1

What is the measure of the angle at the tail end of the kite? if the top area is where its pointed is 122?

nataly862011 [7]

Answer:

The angle is 58 degrees

Step-by-step explanation:

Given

See attachment for kite

Required

The angle at the tail end

Represent this angle with x.

From the attached kite, we have:

1 angle = 122

2 angles = right-angled

So, we have:

$x + 122 +90+90 = 360$ --- sum of angles in a kite

$x + 302 = 360$

Solve for x

$x =- 302 + 360$

$x =58^\circ$
