Please Help. The Topic Is Angles. Anything You Know Helps

Answers

Answer 1

Answer:

all of them except straight and reflex

Step-by-step explanation:

when angles are supplementary it means that they add up to 180

an acute angle is supplementary to an obtuse angle

an obtuse angle is supplementary to an acute angle

a right angle is supplementary to a right angle

but a reflex angle is over 180 so it's not supplementary to anything

and a straight angle is already 180 so it has no supplements either

What does this equal too(2x-5)^2

Answers

Answer:

4x² - 20x + 25

Step-by-step explanation:

(2x-5)² means (2x-5)(2x-5)

Expand the brackets.

1. do 2x times 2x = 4x²

2. do 2x times -5 = -10x

3. -5 times 2x = -10x

4. -5 times -5 = 25

Altogether it is 4x² - 10x - 10x + 25

This simplifies to 4x² -20x + 25.

What is Congruence of Triangles?

Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.

Given is a proof for the congruence of the lines HG and EG.

Given,

G is the midpoint of KF.

KH ∥ EF

Triangles F E G and K H G are connected at point G.

We have to prove HG ≅ EG.

From the given steps of proof,

we get two angles and the included side of triangle FEG is congruent to corresponding two angles and the included side of triangle KHG.

So by ASA theorem both triangles are congruent.

Hence the missing reason is ASA.

Please help

Answers

Answer:

[tex]x = 52[/tex]

Step-by-step explanation:

We have the following equation:

[tex]3x -17=2x+35[/tex]

First we simplify the numbers.

[tex]3x -17+17=2x+35+17[/tex]

[tex]3x=2x+52[/tex]

[tex]3x-2x=2x-2x+52[/tex]

[tex]x=52[/tex]

Answer:

x = 52

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define equation

3x - 17 = 2x + 35

Step 2: Solve for x

Subtract 2x on both sides:                           x - 17 = 35Add 17 to both sides:                                    x = 52

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                         3(52) - 17 = 2(52) + 35Multiply:                             156 - 17 = 104 + 35Subtract/Add:                    139 = 139

A community hall is shape of a cuboid. The hall is 40 m long, 15 m wide and 3 m high. The community hall needs re-decorating with new point for the walls and ceiling, and new tiles on the floor. A 10 litre tin of paint covers 25m*25m and costs £10. 1m*1m floor tiles cost £3 each. Work out the total cost of paint and tiles needed to re-decorate the community hall.

Answers

Total cost for tiles and paints is $924.
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.



Therefore, the area of walls and ceiling is 1410 square meters.
Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore,


Therefore, the total painting cost is $564.
Tiles will be required for floor. Let us find the area of floor.


Given: 1m squared floor tiles costs $3. So,

Therefore, the total cost for tiles is $360.
Now let us find combined total cost of tiles and paint.

Therefore, the combined total cost of tiles and paint is $924.
