Find the value of x. Diagram not to scale

We first need to find the sum of the interior angles in a pentagon, which you do by doing (5 - 2) × 180, which equals 3 × 180 = 540°. Now you know that all of the angles inside the shape must add up to 540, so you can make an equation:
90 + 112 + 2x + 148 + 2x + 10 = 540
360 + 4x = 540
- 360
4x = 180
÷ 4
x = 45

I hope this helps!

What is the standard form equation of the line shown below? (1 point)
kaheart [24]

Answer:

Choice 1.  -3x + 2y = 5.

Step-by-step explanation:

The slope of the line = y2-y1/x2-x1

= (4 - 1) / (1 - (-1))

= 3/2.

To find the equation of the line we use the point-slope form of the equation of a line:

y - y1 = m(x - x1)  where m = slope and (x1, y1) is a point on the line. So using m = 3/2 and the point (1, 4):

y - 4 = 3/2(x - 1)

y - 4 = 3/2 x - 3/2

Multiply through by 2:

2y - 8 = 3x - 3

-3x + 2y = -3 + 8

-3x + 2y = 5 (answer).

Assume that the probability that a baseball player will get a hit in any one at bat is 0.250. What is the probability that he wi
Yanka [14]

Answer: 0.0791

Step-by-step explanation:

Given : The probability that a baseball player will get a hit in any one at bat is 0.250.

Let x be the first hit.

According to the geometric probability , the probability that x (th) trial is the first success =P(X=x)=(1-p)^{x-1}p , where p is the probability of getting success in each trial.

As per given p= 0.250

Then, the probability that he will get his first hit on his 5th at bat will be :

P(X=x)=(1-0.25)^{5-1}(0.25)\\\\=(0.75)^4(0.25)\\\\=0.0791015625\approx0.0791

Hence, the probability that he will get his first hit on his 5th at bat is 0.0791 .

Find the area of the figure.<br><br> A) 114 cm2 <br> B) 350 cm2 <br> C) 418 cm2 <br> D) 447 cm2
NISA [10]
Square has 4 equal sides so it would be the same for all the corresponding sides.

area of square = s*s

                        = 19*19

                       = 361cm^2

area of triangle = \frac{hb}{2}

                         = 19*6

                         = 114/2

                         = 57cm^2

total area = 57+361=418cm^2
