Answer 1

C using Pythagorean theorem

Answer 2

Answer:

√97 units

Step-by-step explanation:

AB represents the largest side of the triangle so in order to solve for that side, use Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2
where a = height b = base and c = the largest side

Step 1. Find the length of AC (represented as a)

Answer: 9 units

Explanation: either count how many units or use the distance formula

Step 2. Find the length of CB (represented as b)

Answer: 4 units

Explanation: either count how many units or use the distance formula

Step 3. Substitute a for 9 and b for 4 units in Pythagorean Theorem

9^2 + 4^2 = c^2

Step 4. Simplify the exponents

81 + 16 = c^2

Step 5. Solve for c^2

c^2 = 81 + 16

c^2 = 97

Step 6. Square root c^2

c = √97

Answer:

Step-by-step explanation:

The angles are vertically opposite. Vertically opposite angles are equal.

12x - 5 = 10x + 1 Add 5 to both sides.

12x = 10x + 5 + 1 Combine

12x = 10x + 6 Subtract 10x from both sides.

12x - 10x = 6 Combine

2x = 6 Divide by 2

x = 6/2

x = 3

Adjacent angles to each other when sharing a side are supplementary

4x + 7 + 2x + 5 = 180 Combine like terms on the left

6x + 12 = 180 Subtract 12 from both sides

6x = 180 - 12 Combine

6x = 168 Divide by 6

x = 168 / 6

x = 28

[tex] \displaystyle \large \tt{ \sin a = \frac{opposite}{hypotenuse} }[/tex]

First, we have to focus on ∠a, at the angle a or ∠a, the opposite is z because ∠a is the opposite side of z.

The hypotenuse side is always x, even if we change from ∠a to ∠b (b = 90°-a)

So what we have now are:

opposite = z (Refer to the bold text)hypotenuse = x (hypotenuse is always the side that is opposed to a right angle.)

Substitute the letter in the ratio:

Answers

Answer:

The scale of a map is 1:250000.The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimetre

Step-by-step explanation:

1 m = 100 cm

1 km = 1000 m = 100 000 cm

1:250 000 mean that 1 cm on the map represents an actual distance of 250 000 cm = 2.5 km

1:250 000 = 2.5 km / cm

80 km / 2.5 km / cm = 32 cm

80 km = 8 000 000 cm

8 000 000 cm ∙ 1 / 250 000 = 8 000 000 cm / 250 000 = 32 cm

1. Find the distance between the pair of points: (-8, -2) and (-4,5)

Answers

Hi, I'm happy to help!

To solve, this, we need to find the distance in x coordinates, y coordinates, then use the Pythagorean Theorem, let's solve!

First, we have to find the distance in x coordinate values. The first coordinate is -8, and the second is -4, which means there is an x distance of 4.

Next, we need to find the distance in y coordinate values. The first coordinate is -2, and the second is 5, meaning there is a y distance of 7.

From here, we use the Pythagorean Theorem. This states that a²+b²=c².

This applies to right triangles, which is what we have. The x distance is a, the y distance is b, and the overall distance is c. We need to find c to answer the question. Let's plug in our values:

4²+7²=c²

16+49=c²

65=c²

To find c, we need to find the square root of 65.

√65

8.0622577...

Rounding to the nearest tenth is 8.1.

The distance between the two points is about 8.1.

use the diagram on the right. How many planes contain both the line and the point

a. FG and point P

b. EP and point G

Answers

Part (a)

Answer: 0

-------------------

Explanation:

Point P is part of 3 planes or faces of this triangular prism:

plane PEF (the front slanted plane)plane PEH (the left triangular face)plane PHG (the back rectangular wall)

Notice how each three letter sequence involves "P", though this isn't technically always necessary. I did so to emphasize how point P is involved with these planes.

Each of the three planes mentioned do not involve line FG

Plane PEF only deals with point FPlane PEH doesn't have any of F or G involvedplane PHG only involves G

So there are no planes that contain line FG and point P.

==================================================

Part (b)

Answer: 0

-------------------

Explanation:

It's the same idea as part (a) earlier. The planes involving point G are

plane GQF (triangular face on the right)plane GFE (bottom rectangular floor)plane GHP (back rectangular wall)

None of these planes have line EP going through them.

As an alternative, we could reverse things and focus on all of the planes connected to line EP. Those 2 planes are

plane PEH (triangular face on the left)plane PEF (front slanted rectangular face)

None of these planes have point G located in them.
