Answer:

∠ F = 94°

Step-by-step explanation:

The opposite angles of the quadrilateral are supplementary, thus

∠ D + ∠ F = 180°, that is

86° + ∠ F = 180° ( subtract 86° from both sides )

∠ F = 94°

Answer:

Step-by-step explanation:

Angle <D is an inscribed angle and the measure of it is equal to the half of the arc it sees

so the measure of arc EFG is 2×86° = 172°

Since the perimeter of a circle is 360° the measure of arc EDG would be 360 - 172 = 188

Therefore since the measure of angle <F should be half of the arc it sees as well the answer is 188 ÷ 2 = 94

The correct answer is 7.2

We can subtract 2 from 4, which is 2.

They're both in the same decimal place, so that is why they are affecting each-other.

Evaluate the Expression<br> When X=2, 3x-1=

Alex777 [14]

Answer:

Step-by-step explanation:

If X equals 2, then 3 times X would be 6. This is because if a number and a variable are put together, you have to multiply them. 6-1 is 5.

Out of 18 people in a room, 2 have red hair. What is the probability that a person picked at random from the room does NOT have

Mariana [72]

Answer :

Total number of people in the room = 18

Number of people with red hair = 2

Number of people not with red hair = 18 - 2 = 16

Probability of picking a person who doesn't have red hair = $\sf\dfrac{Number\:of\:favourable\:outcomes}{Total\:outcomes}$

Probability = 16/18

Reduce the fraction with 2

Probability = 8/9

At a certain time of day, the angle of elevation of the sun is 80degree. Find the height of a tree whose shadow is 44 feet long.

Arte-miy333 [17]

The height of the tree is 249.5 feet

<h3>How to determine the height of the tree?</h3>

The given parameters are:

Elevation angle = 80 degrees
Shadow length (L) = 44 feet

Let the height of the tree be x.

So, we have:

tan(80) = x/44

Multiply both sides by 44

x = 44 * tan(80)

Evaluate

x = 249.5

Hence, the height of the tree is 249.5 feet
