Describe And Correct The Error In Using Properties Of Parallelograms.

Answers

Answer 1

Answer/Step-by-step explanation:

Opposite angles of a parallelogram are equal to each other.

Therefore, <S = <U, and <T = <V

Consecutive angles of a parallelogram are supplementary.

Therefore,

m<S + m<V = 180°

50° + m<V = 180°

m<V = 180° - 50° (subtraction property of equality)

m<V = 130°

Step-by-step explanation:

Need to know the following angle

Answers

Given:

[tex]m\angle A=(2x-15)^\circ[/tex]

[tex]m\angle B=(x-5)^\circ[/tex]

[tex]\text{Exterior}\ m\angle C=148^\circ[/tex]

To find:

The [tex]m\angle ABC[/tex].

Solution:

In triangle ABC,

[tex]\text{Exterior}\ m\angle C=m\angle A+m\angle B[/tex]          [Exterior angle theorem]

[tex]148=(2x-15)+(x-5)[/tex]

[tex]148=3x-20[/tex]

[tex]148+20=3x[/tex]

[tex]168=3x[/tex]

Divide both sides by 3.

[tex]\dfrac{168}{3}=x[/tex]

[tex]56=x[/tex]

Now,

[tex]m\angle ABC=(x-5)^\circ[/tex]

[tex]m\angle ABC=(56-5)^\circ[/tex]

[tex]m\angle ABC=51^\circ[/tex]

Therefore, [tex]m\angle ABC=51^\circ[/tex].

amid has gained weight he now weighs 88kg which is 10% higher than his normal weight. what is his normal weight?

Answers

Answer:

88*0.9= 79.2 (since it's 10% higher, multiply by .9 to find out what 90% of 88 is

you also could've done 88*0.1=8.8 and then subtract 8.8 from 88 and get 79.2

either way his normal weight is 79.2kg

{2x+y=16

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The system of equations to find the cost of large and small candles are,

4x + 3y = 34

2x + y = 16

Option D is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 4 - 8 is an equation.

We have,

At Yankee Candle, four large candles and three small candles sell for $34. For two large candles and one small candle, the cost is $16.

Large candles = x

Small candles = y

Now,

4x + 3y = 34

2x + y = 16

Thus,

The system of equations to find the cost of large and small candles are,

4x + 3y = 34

2x + y = 16

Option D is the correct answer.
