I need help! Find the measure of the indicated angle to the nearest degree.

Mathematics

Klio2033 [76]3 years ago

Seeing as this is a right triangle, we would solve for the unknown angle using a trigonometric function.

Remember! SOH-CAH-TOA

Looking from the unknown angle, we are given the adjacent side and the hypotenuse. Therefore, we should use the cosine function.

cos(?) = 17 / 19

---To find the unknown angle measure, you will need to use the inverse cosine function. This function is generally found by using the "2nd" button on your calculator and then pressing the cosine button. It should look like one of the following options: "cos^-1" or "arccos".

Make sure your calculator is in degrees, not radians!

cos^(-1) [17/`9]

26.52

---Round to the nearest degree per the instructions

Answer: 27 degrees

Hope this helps!

Parallelogram with vértices (-10,7) , (7,-4), and (-10,-2)
kkurt [141]
So basically in any paralellogram you have 2 pairs sides that are equal length and that are paralell to each other

hmm

we look at them that we have and look for matches

the only match we got is (-10,7) and (-10,-2)
means that one side is from (-10,7) o (-10,-2) and is 9 units long goint up
that (7,-4) must be the other poinr of the other side
since -4<-2, the missing point must be 9 units up from (7,-4)
9-4=3

(7,5) is the missing point

Divide x4 + 7 by x - 3.. A] x³ - 3x² - 9x - 27 R 88. B] x³ + 3x² + 9x - 27 R -74. C] x³ + 3x² + 9x + 27 R 88

<span> divide a polynomial p(x) by (x-3). Add and subtract the multiple of (x-3) that has the same highest-power term as p(x), then simplify to get a smaller-degree polynomial r(x) plus multiple of (x-3). </span>

<span>The multiple of (x-3) that has x^4 as its leading term is x^3(x-3) = x^4 - 3x^3. So write: </span>

<span>x^4 + 7 = x^4 + 7 + x^3(x - 3) - x^3(x - 3) </span>
<span>= x^4 + 7 + x^3(x - 3) - x^4 + 3x^3 </span>
<span>= x^3(x - 3) + 3x^3 + 7 </span>

<span>That makes r(x) = 3x^3 + 7. Do the same thing to reduce r(x) by adding/subtracting 3x^2(x - 3) = 3x^3 - 9x^2: </span>

<span>= x^3(x - 3) + 3x^3 + 7 + 3x^2(x - 3) - (3x^3 - 9x^2) </span>
<span>= x^3(x - 3) + 3x^2(x - 3) + 9x^2 + 7 </span>

<span>Again to reduce 9x^2 + 7: </span>
<span>= x^3(x - 3) + 3x^2(x - 3) + 9x^2 + 7 + 9x(x - 3) - (9x^2 - 27x) </span>
<span>= x^3(x - 3) + 3x^2(x - 3) + 9x(x - 3) + 27x + 7 </span>

<span>And finally write 27x + 7 as 27(x - 3) + 88; </span>
<span>x^4 + 7 = x^3(x - 3) + 3x^2(x - 3) + 9x(x - 3) + 27(x - 3) + 88 </span>

<span>Factor out (x - 3) in all but the +88 term: </span>
<span>x^4 + 7 = (x - 3)(x^3 + 3x^2 + 9x + 27) + 88 </span>

<span>That means that: </span>
<span>(x^4 + 7) / (x - 3) = x^3 + 3x^2 + 9x + 27 with a remainder of 88</span>

If you have 50g of sugar and want to make 25% sugar syrup,<br> how much water do you need?
Taya2010 [7]

Answer:

3(50 g) = 150 g

Step-by-step explanation:

If you mean 25% sugar by mass, then 1/4 of the total mass is sugar, and 3/4 is water.  So you need 3 times as much water as sugar.

3(50 g) = 150 g

Identify the perimeter of a rectangle in which h=8 ft and A=144x ft2.
WINSTONCH [101]

Answer:

52ft

Step-by-step explanation:

perimeter of a rectangle = 2 (height+ breath)

Area of a rectangle = height× breath

144= 8×L

L= 144/8 = 18ft

perimeter= 2(8+18)

perimeter= 2(26)= 52ft
