The measurement of the complement of an angle is 39 degrees more than the angle. Find the measurement of the angle and its compl

olga_2 [115]

Let "a" represent the angle. Then its complement is (90-a). The complement is 39° more than the angle, so we have
(90-a) - a = 39
51 = 2a
25.5 = a

The measure of the angle is 25.5°; its complement is 64.5°.

The width of the rectangle is 60% of it length which is 40 feet. What is the area of the rectangle?

valina [46]

I hope this is correct,

It says the width is 60% of the rectangles length,

.60 • 40 = 24(Width)

Then to find out the area you just multiply the length times the width

24 • 40 = 960

Again hope this is correct.

The linear combination method gives a solution of (–4, 2) for which of these systems of linear equations?

Andrew [12]

Answer:

$3x + 13y = 14$

$6x + 11y = -2$

Step-by-step explanation:

<em>See Attachment for complete question</em>

To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;

Given that

$(x,y) = (-4,2)$

Testing Option A

$3x + 13y = 14$

$6x + 11y = -2$

Substitute $x = -4$ and $y = 2$ in $3x + 13y = 14$

$3(-4) + 13(2) = 14$

Open Brackets

$-12 + 26 = 14$

$14 = 14$

Substitute $x = -4$ and $y = 2$ in $6x + 11y = -2$

$6(-4) + 11(2) = -2$

Open Brackets

$-24 + 22 = 2$

$2 = 2$

<em>In both cases, the expression on the right hand side equates to that on the left hand side; </em>

<em>Hence, there's no need to check for other options. </em>
