Answer:

x = 9

Step-by-step explanation:

We know sum of interior angles of a polygon = $(n-2)\times 180$

For a triangle (having n = 3),

Sum of interior angles = (3 - 2)×180°

= 180°

In ΔVWX,

m∠V = (12x + 19)°

m∠W = (2x + 19)°

m∠X = (x + 7)°

And m∠V + m∠W + m∠X = 180°

(12x + 19)° + (2x + 19)° + (x + 7)° = 180°

(12x + 2x + x) + (19 + 19 + 7) = 180°

15x + 45° = 180°

15x = 180° - 45°

x = $\frac{135}{15}$

x = 9

Therefore, value of x = 9.

A number cube is labeled 1 through 6. What is the probability of NOT<br> rolling a 2?

Andre45 [30]

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

1 2 3 4 5 6

1/6 1/6 1/6 1/6 1/6 1/6

Every time the cube is rolled there is a 6/6 chance of any number comes up

1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1

What is the probability of NOT rolling a 2? Any other number

1 2 3 4 5 6

1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333

Identify the digit in the ten thousandths place in every number.

Lady bird [3.3K]

Answer:

Step-by-step explanation:

The decimal point will help you find your way here. Just to the right of the decimal is the tenths place. 0.4 is the number four tenths.

Next, farther to the right is the hundredths place-- 0.04 is the number four hundredths.

Next over is the thousandths place-- 0.004 is the number four thousandths. And finally, the next over is the ten thousandths place...like this, 0.0004 is the number four ten thousandths

So, 1) 12.00535 has a one in the tens place, a two in the ones place, zeros in the tenths and also the hundredths places, fives in the thousandths place and also the hundred thousandths place, AND, what you're looking for-- a 3 in the ten thousandths place.

1) 3

2) 4

3) 5

4) 6

5) 7

6) 8

7) 9

For ten thousandths place, you're looking at the fourth spot on the right side of the decimal.

F) One number is 78 more than

vladimir2022 [97]

Answer:

The larger number = 116

Step-by-step explanation:

Let the smaller number = x

Given that one number is 78 more than another, so

The larger number = x+78

Given that if we add 12 to the smaller number, the result is 50, so

$x+12=50$

subtract 12 from both sides

$x+12-12=50-12$

Simplify

$x=38$

Therefore,

The smaller number = 38

The larger number = x+78 = 38+78 = 116

Thus, the larger number = 116
