Answer:

a=15x; b=8x; c=13x

180°=a+b+c=15x+8x+13x=36x

=> x=180÷36=5

=> a=15×5=75°; b=8×5=40°; c=13×5=65°

Answer:

[x + 2][x + 5][x - 1]

Step-by-step explanation:

The Leading Coefficient is 1 and the initial value is 10; they have a common factor of 1, so that automatically gives us our first factor of [x - 1]. Now, since the divisor\factor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

1| 1 6 3 −10

↓ 1 7 10

__________

1 7 10 0 → {x}^{2} + 7x + 10 >> [x + 2][x + 5]

You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [x³ + 6x² + 3x - 10]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², the 7x follows right behind it, then 10, giving you the other factor of {x}^{2} + 7x + 10, which can be factored further to [x + 2][x + 5], attaching this to the first factor you started out your work on:

[x + 2][x + 5][x - 1]

Below are two parallel lines with a third line intersecting them. What is x
sleet_krkn [62]

Answer:

136=x

Step-by-step explanation:

When an angle is shown, the one opposite of it is equal to the forst equation. The bottom angles are equal to 360ñ so if you take 46x2=92. Subtract 92 by 360 to get 268. Divide it by 2 to get one of the bigger angles, which is 134 degrees. And as for the top, one angle on the bottom is equal to the same spot on the top. so, 136=x

GEOMETRY HELP! Celeste is constructing the perpendicular bisector of ST⎯⎯⎯⎯⎯ . Which set of instructions explains a correct way
Elan Coil [88]

Answer:

The answer is C.

Step-by-step explanation:

Given the line segment ST. we have to give the instruction to construct the perpendicular bisector of line ST.

So to construct the perpendicular bisector of line our first step is to place the compass at one end of line and then adjust the compass more than half of line segment and draw the arc on each side of segment.

After that Keeping the same compass width, draw arcs from other end of line. Place scale where the arcs intersect, and draw the line segment.

So, the correct match is option C )  Place the compass point on point S and open the compass so that the pencil point is on the segment, but closer to point T than to point S. Draw an arc on each side of segment.

What are all the integers for z/x33 xy/98 and 45
Ymorist [56]

Answer:

im pretty sure i got it correct inverse operations since we can say. 2 2 x x. + - = . If we start with x, then add 2 and subtract 2, ... multiplication and division, squares and square roots (for positive numbers), ... The bottom line is obviously false, and so are all of the previous lines. ... 98 x. -. -. = -. 19. 3 5 3 1 x+ - = 20. 2 3 4 7 x - + = 21. (. )3. 1. 1. 8 x-. = 22

Johnny bought an oil painting originally priced at $80 but on sale for for 50% off. After 10% sales tax, what was the total cost
Alecsey [184]

Answer:

$44

Step-by-step explanation:

Original price = $80

Discount on sale = 50%

Discounted price = (1 - 50%) * original price

Discounted price = 0.5 * $80 = $40

Sales tax = 10%

Sales tax amount = 0.1 * $40 = $4

Total cost = discounted price + sales tax amount

Total cost = $40 + $4 = $44
