Answer:

it is B) 95

Step-by-step explanation:

supplementary mean equals to 180. in a triangle problem all the angles should add up to 180. so you take 180 and subtract the number you already have which is 85 and you get 95

Answer:

B. 95º

Step-by-step explanation:

Supplementary angles are ones that add up to 180º.

So if angle 1 is 85º, then the equation would be:

(x-the measure of angle 2)

X + 85 = 180

Solve for x:

X + (85-85) = 180-85

X = 95.

Hope this helps! Have a great day!

The distribution of bladder volume in men is approximately normal with mean 550 ml and standard deviation 100 ml. what percent o

ruslelena [56]

To solve this, we use the z-test.

z = (x – u) / σ

when x = 450

z = (450 – 550) / 100

z = -1

We use the standard distribution tables to find for P.

P = 0.1587

Since we are looking for values greater than x = 450, therefore:

1 – 0.1587 = 0.8413

This means that 84.13% have bladder volume larger than 450 mL.

Help me with those two questions

Ksenya-84 [330]

Given:

A figure in which a transversal line intersect two parallel lines.

$m\angle 2=4x+7, m\angle 7=5x-13, m\angle 5=68$ and $m\angle 3=3y-2$ .

To find:

The value of x and y.

Solution:

We know that, if a transversal line intersect two parallel lines, then

(1) Alternate exterior angles are equal.

(2) Same sided interior angles are supplementary. So their sum is 180 degrees.

In the given figure j and k are parallel lines and l is a transversal line.

From the given figure, it is clear that,

$m\angle 2=m\angle 7$ (Alternate exterior angles are equal)

$4x+7=5x-13$

$7+13=5x-4x$

$20=x$

Therefore, the value of x is 20.

Now,

$\angle 3+\angle 5=180$ (Same sided interior angles are supplementary)

$3y-2+68=180$

$3y+66=180$

$3y=180-66$

$y=\dfrac{180-66}{3}$

$y=\dfrac{114}{3}$

$y=38$

Therefore, the value of y is 38.

Circle O has a circumference of approxim

aev [14]

Answer:

80 ft

Step-by-step explanation:

Circumference is approximately 250 ft

We want to find the diameter.

Circumference of a circle = π × D (D is the diameter)

So πD ≈ 250 ft

D ≈ $\frac{250}{Pi}$ ≈ 79.57747155

Diameter is approximately 80 ft.
