Step-by-step explanation:

Answer:

m∠A = 58°

Step-by-step explanation:

In ΔABC,

m∠BAC = (x + 63)°

m∠ABC = (x + 96)° [Vertically opposite angles]

m∠ACB = (180° - 149°)

             = 31°

By triangle sum theorem,

m∠ABC + m∠ACB + m∠BAC = 180°

(x + 96) + 31 + (x + 63) = 180°

2x + 190 = 180

2x = -10

x = -5

Therefore, measure angle A = (x + 63)

                                               = -5 + 63

                                               = 58°

Step-by-step explanation:

We can use pythagorean theorem [tex](a^2+b^2=c^2)[/tex] where a and b are sides of a right triangle and c is the hypotenuse.

[tex]x^2+13.3^2=15.4^2[/tex].

[tex]x^2=15.4^2-13.3^2\\[/tex]

[tex]x^2=237.16-176.89\\x^2=60.27\\x=7.763[/tex]

Rounded to the nearest tenth, x = 7.8

Step-by-step explanation:

Answer:

b=18.76

Step-by-step explanation:

Let the line that splits the big triangle into two small triangles be x.

Let the unmarked side of the big triangle be y.

Consider the big triangle. By Pythagorus:

(6+16)²=b²+y²

484=b²+y²

y²=484-b²

Consider the small left triangle. By Pythagorus:

y²=6²+x²

y²=36+x²

x²=y²-36

Consider the small right triangle. By Pythagorus:

b²=16²+x²

b²=256+x²

b²=256+x²

b²=256+y²-36

b²=220+y²

b²=220+484-b²

2b²=704

b²=352

b=18.7616630393

b=18.76

Step-by-step explanation:

where,

finding the area of circle

⟼ A = πr²

⟼ A = 22/7 × 5²

⟼ A = 22/7 × 5 × 5

⟼ A = 3•14 × 5 × 5

⟼ A = 3•14 × 25

⟼ A = 78•5

∴ the area of circle is 78•5 centimeters

Answer  The value of x can be found from eqautions or graphs

Step-by-step explanation:

Hi! So there is no equation, image, or otherwise added here which would make it difficult to answer your question. X is always changing based on the situation. But if you have an equation you should be able to simplify the equation and then take the quadratic formula to get the value of x. If you have  a graph you can find the rise/run. Sorry I cannot help more and I hope you find what you are looking for!

Answer:

2%

Step-by-step explanation:

Hello, to find the percentage of 8 and 400, you simply divide 8 over 400 and you get 2%.

Answer:

2%

Step-by-step explanation:

[tex]\frac{8}{400} =\frac{y}{100}[/tex]

Cross multiply.

400y = 800

400y ÷ 400 = 800 ÷ 400

y = 2

Answer:

I think its 5x²-27x+10

Step-by-step explanation:

Area of trapezium:

a+b/2× h

So substitute into the formula:

4x - 1 + 6x - 3 /2 × (x - 5)

1. 4x - 1 + 6x - 3 (collect all like terms)

4x + 6x + -1 -3 = 10x - 4

2. 10x - 4 / 2

= 5x - 2

3. 5x - 2 × x - 5

Use FOIL:

5x ² - 25x - 2x + 10

= 5x ² - 27x +10

Answer:

Step-by-step explanation:

Alexis earned to equal Eduardo earned in how many weeks

Alexis earned           115 + 50w = Total        w equals weeks

Eduardo earned      130 + 40w = Total        w equals weeks

subtract equations    -15 + 10w =  0

                                            10w = 15

                                             w = 1.5 weeks   they both will have $190

Answer:

A

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

First we find what fraction 8 is of 12. Which is 2/3. With 2/3 we use this fraction with 15 (which is 15/3 = 5 then we multiply this by the numerator which is 2 x 5 = 10) So, 2/3 of 15 is 10.

Y=x^2-2x-8

Step-by-step explanation:

The standard form of the equation y=(x-1)²-9 is y=x²-2x-8

Two or more expressions with an Equal sign is called as Equation.

y=(x-1)²-9 equation is in the form of a quadratic equation

where y is the unknown variable and x is the known variable.

The equation can be written in standard form by expanding the (x-1)² term and combining like terms.

y=(x-1)²-9

y=x²+1-2x-9

Combine the like terms

y=x²-2x-8

The expanded form of the equation is y=x²-2x-8

Hence, the standard form of the equation y=(x-1)²-9 is y=x²-2x-8
