A roof has the shape of an isosceles triangle with equal sides 8 cm long and base 12 m long. What is the measure of the angle of

victus00 [196]

Answer:

41 degrees to the nearest degree.

Step-by-step explanation:

A line drawn from the vertex and bisecting the base forms 2 right triangles.

The base of one right triangle = 1/2 * 12 = 6 m.

So cos A = adjacent side /hypotenuse where A is the angle of inclination.

cos A= 6 / 8 = 0.75

m < A = 41.41 degrees.

Simplify completely quantity 4 x squared minus 32 x plus 48 all over quantity 3 x squared minus 17 x minus 6.

Yuki888 [10]

For this case we must simplify the following expression:

$\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6}$

Simplifying the numerator, dividing all the terms by 4, we have:

$x ^ 2-8x + 12$

We factor by looking for two numbers that when added together give -8 and when multiplied by 12. These are: -6 and -2

$-6-2 = -8\\-6 * -2 = 12$

So, we have to:

$x ^ 2-8x + 12 = (x-6) (x-2)$

Simplifying the denominator:

We rewrite -17x as -18x + x:

$3x ^ 2-18x + x-6$

We factor the highest common denominator of each group:

$3x (x-6) +1 (x-6)$

We factor the polynomial by factoring the highest common denominator (x-6):

$(x-6) (3x + 1)$

So, we have to:

$3x ^ 2-17x-6 = (x-6) (3x + 1)$

Substituting in the original expression we have:

$\frac {(x-6) (x-2)} {(x-6) (3x + 1)} = \frac {x-2} {3x + 1}$

ANswer:

$\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6} = \frac {x-2} {3x + 1}$

Dustin needed 0.80 meter of fabric to make a pillow. The fabric cost $1.50 per meter. How much did Dustin pay for 0.80 meter of

aliina [53]

Given parameters:

Length of fabric needed to make a pillow = 0.8m

Cost of fabric per meter = $1.5

Unknown:

Cost of the 0.8m fabric = ?

Solution:

The cost of the fabric = cost per meter x length of fabric

Input the parameters and solve;

Cost of the fabric = 0. 8 x 1.5 = $1.2

Dustin will have to $1.2 for the fabric

Answer:

x = 2

Step-by-step explanation:

BO = OD

they are apart of the same line segment with O as the midpoint of BD

since they're equal set equal and solve for x

7x + 4 = 18 subtract 4 from both sides

7x = 14 divide both sides by 7

x = 2
