Angle 3 and angle 4 are supplementary. Angle 3 equals 5x + 15 and angle 4 equals 10x. What does x equal

Mathematics
1 answer:
NNADVOKAT [17]3 years ago
8 0

Answer:

X = 11

Step-by-step explanation:

since the angles are supplementary that means their sum is 180

<em>5x + 15 + 10x = 180 \\ 15x + 15 = 180 \\ 15x = 180 - 15  \\ 15x = 165 \\ x = 165  \div 15 \\ x = 11</em>

The product of two consecutive odd integers is 195.
rodikova [14]

You need the odd integers to be separated by 2. One will not work.

If n is odd, n + 1 will be even. You cannot get an exception to that. Try it.

1 is odd but 1 + 1 is even.

n and n + 3 produces 1 odd and 1 even. If n is odd then since 3 is odd when the two are added together, you get an even.  Again try it

n = 5

n + 3 = 8

C: is not the answer.

D can't work either. If n is odd then n + 2 will be odd but n + 1 is even.

The Answer is B.

n(n + 2) = 195

n^2 + 2n - 195 = 0

(n - 13)(n + 15)

n can be 13 and n + 2 can be 15

13 * 15 = 195

But here's something you may not know

n can be - 15 and then the other odd number would be - 13

Round 389,422 to the ten thousand
frosja888 [35]
To round 389,422 to the ten thousand, you need to go to the second number which is 8 and round it to the right. To the right of 8 is 9 so if a number is more than 5 you round 8 to 9. Then all the numbers after 8 turn into zeros

So... your answer is:

390,000

In ΔBCD, the measure of ∠D=90°, CB = 25, BD = 7, and DC = 24. What is the value of the sine of ∠C to the nearest hundredth?
skad [1K]

Answer: The value of the sine of ∠C is 0.28.

Step-by-step explanation:

Let's draw a triangle again (see the picture below).

Remember SOHCAHTOA? It's:

-sin = opposite/hypotenuse

-cos = adjacent/hypotenuse

-tan = opposite/adjacent.

We need to use sin in here.

The sin of C is \frac{7}{25}, which in a calculator, gives 0.28
