Answer:

the measure of angle A: 18.6°

measure of angle B: 55.8°

measure of angle C: 105.6°

Step-by-step explanation:

6x - 6 + 3x + x = 180

10x - 6 = 180

10x (- 6 + 6) = 180 + 6

10x = 186

10x/10 = 186/10

x = 18.6

18.6 + 3(18.6) + [6(18.6) - 6] = 180

18.6 + 55.8 + 105.6 = 180

180 = 180

The area of a rectangular mirror is 15 7 16 square feet. The width of the mirror is 3 1 4 feet. If there is a 5 foot tall space

Vlad1618 [11]

Given:

Area of rectangle = $15\dfrac{7}{16}$ sq. feet.

Width of the mirror = $3\dfrac{1}{4}$ feet.

To find:

Whether it will fit on the wall whose length is 5 foot.

Solution:

We know that, area of a rectangle is

$Area=length\times width$

$\dfrac{Area}{width}=length$

Substituting the given values, we get

$Length=\dfrac{15\dfrac{7}{16}}{3\dfrac{1}{4}}$

$Length=\dfrac{\dfrac{15\times 16+7}{16}}{\dfrac{3\times 4+1}{4}}$

$Length=\dfrac{\dfrac{240+7}{16}}{\dfrac{12+1}{4}}$

$Length=\dfrac{\dfrac{247}{16}}{\dfrac{13}{4}}$

$Length=\dfrac{247}{16}\times \dfrac{4}{13}$

$Length=4.75
$

So, length of mirror is 4.75 feet which is less than 5 feet.

Therefore, the mirror will fit on the wall.

Find the value of X in X-X³=17

Karolina [17]

Answer:

Step-by-step explanation:

Step1: find the interval of roots. Consider -3 and -2

$f(-3) = -7$

$f(-2) = 18 >0$

Hence, the root must be on [-3,-2]

Step2: consider the middle point -2.5

$f(-2.5) = 3.875 >0$

Then, the root must be on [-3, -2.5]

Step 3: Repeat step 2 by finding the value of f at the middle point -2.75

$f(-2.75) = -1.0468$

Step 3: Repeat step 2 by finding the value of f at the middle point of the interval [-2.75,-2.5] which is -2.625

$f(-2.625) = 1.537 >0$

Step4: Repeat step 2 on [-2.75, -2.625]

Repeat step 2 until you got the root which is -2.701
