Measure of angle TRV?

Mathematics
1 answer:
Helga [31]2 years ago
6 0

Answer:

130 degrees

Step-by-step explanation:

We know (x-10)+(2x+10) is 180 degrees.

So first we need to find x. (x-10)+(2x+10)=3x

3x=180

x=60

Angle TRV is 2x+10.

If we input 60 in the place of x, it is 2(60)+10=120+10=130.

The answer is 130 degrees.

14 less than a number all divided by the same number
Fynjy0 [20]

Answer:

(n-14) / n

n is your number;

"14 less" means "subtract 14", --> we have (n-14);

now we need to divide (n-14) by same number as your number, which is "n"---> final expression is:  (n-14)/n

8090 [49]
Given that the value of an industrial machine has a decay factor of 0.75 per year, and after six years, it became $7,500 only, this would mean that the original value of the machine would be solved like this: <span>7500 = x(1-.75)^6 
</span>7500 = x(0.25)^6
7500 = x(<span>0.00024414062)
7500 = </span><span>0.00024414062x
x = </span><span>30, 720, 000

What method did you use? Why? Solve. for x: 47° 13​
Kazeer [188]

Answer:

Step-by-step explanation:

Givens

You have the hypotenuse: 13

You seek the adjacent side: x

You have the angle enclosing the 2: 47 degrees.

The relationship is the Cosine

Solution

Cos(47) = opposite / hypotenuse

Cos(47) = 0.6820                            From your calculator

Cos(47) = x / 13                                Multiply both sides by 13

13*cos(47) = x

x=8.866
