Answer:

sin A = 40/41

tan A = 40/9

cos A = 9/41

Step-by-step explanation:

sin theta = opp/ hyp

tan theta = opp/ adj

cos theta = adj/ hyp

We want to find the measures for angle A

sin A = 40/41

tan A = 40/9

cos A = 9/41

Answer:

SinA = opposite/hypotenuse

SinA = 40/41

SinA = 0.976

(0.9756097561)

TanA = opposite/adjacent

TanA = 40/9

TanA = 4.444

(4.44444444)

CosA = adjacent/hypotenuse

CosA = 9/41

CosA = 0.220

(0.2195121951)

Subtract the quantity 10x + 5y - 4z from the sum of the quantities 7z + 3y - 10x and 9x - 12y - z

AleksandrR [38]

Answer:

11x + 14y - 10z

Step-by-step explanation:

firstly deal with sum part and then subtract,making sure that you add and subtract values with the same unknowns

(7z + 3y - 10x) + (9x - 12y - z)

then

(10x + 5y - 4z) - (6z - 9y - x)10

Will give brainliest

Soloha48 [4]

The first slope going up is when the function increases. when the line goes in a straight line it’s constant. abs when the slope goes down it’s decreasing. so in the photo it first increases, stays constant, decreases, stays constant, decreases

3. Find the value of x. 16 10 14 9

Airida [17]

Answer:

x = 9

Step-by-step explanation:

Both the triangles are similar, so the corresponding sides are also similar.

That is,

12 / 8 = x / 6

Cross multiply,

x * 8 = 12 * 6

8x = 72

Divide 8 on both sides,

x = 72 / 8

x = 9

What is the length of segment AC

lakkis [162]

To find the length of segment AC, we must find the total rise and total run between the two points.

Point C is located at (-5, 5). Point A is located at (3,-1). To find the rise, subtract the y-value of A from the y-value of C:

$5 - (-1) = 6$

The rise of this segment is 6.

To find the run, subtract the x-value of A from the x-value of C:

$3 - (-5) = 8$

The run of this segment is 8.

We can use the Pythagorean Theorem to find the length of this segment. The theorem uses the following formula:

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

The segment represents the hypotenuse, and the rise and run represent the legs of this segment. We know that the two legs' lengths are 6 and 8, so plug them into the equation:

$6^{2} + 8^{2} = c^{2}$
$36 + 64 = c^{2}$
$100 = c^{2}$

Square root both sides to get c by itself:

$\sqrt{100} = 10$
$c = 10$

The length of segment AC is 10.
