In parallelogram FGHJ if m∡ GHJ=55˚ find m∡FGH

hodyreva [135]

Answer:

∠ FGH = 125°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, then

∠ FGH + ∠ GHJ = 180° , that is

∠ FGH + 55° = 180° ( subtract 55° from both sides )

∠ FGH = 125°

Factorization is the process of breaking an integer down into its components or divisors, and further calculation can be defined as follows:

Given:

$20x^{2} +124x+24$

To find:

solve the given problem

Solution:

$\to \bold{20x^{2} +124x+24}\\\\\to \bold{4(5x^{2} +31x+6)}\\\\\to \bold{4(5x^{2} +31x+6)}\ \ \ \ \ \ \ \ \ \ \ 5\times 6= 30 \ \ and\ \ 30 \times 1= 30\\\\\to \bold{4(5x^{2} +(30+1)x+6)}\\\\\to \bold{4(5x^{2} +30x+1x+6)}\\\\\to \bold{4(5x(x +6)+1(x+6)}\\\\\to \bold{4((x +6) (5x+1)}\\\\$

Therefore, the final answer is " $\bold{4((x+6)(5x+1))}$ ".

The formula for the area of a triangle is A==bh, where b is the length of the base and h is the height.

zimovet [89]

Answer: Height is 5 units.

Step-by-step explanation:

Alright, lets get started.

The area of the triangle is $A=\frac{1}{2} \times b \times h$

The area is given as 30

The base is given as 12

Plugging the values in formula

$30=\frac{1}{2} \times 12\times h$

$30=6\times h$

Dividing 6 in both sides

$\frac{30}{6}=\frac{6\times h}{6}$

$5=h$

$h=5$

Hence the height of the triangle is 5 units.........Answer

The R-value of insulation is a measure of its ability to resist heat transfer. For fiber-glass insulation, 3½ inches is rated at

Solnce55 [7]

Answer:

$R = \dfrac{16}{5}t + \dfrac{1}{5}$

where R is the R-value and t is the thickness in inches.

Step-by-step explanation:

We are given the following in the question:

The R-value of fiberglass insulation and f its thickness have a linear relation.

Let R be the R-value and t be the thickness. Then, the equation can be written as:

$R = at + b$

where a and b are constants.

When t = 3.5, R = 11

$11 = 3.5a + b$

When t = 6, R = 19

$19 = 6a + b$

Solving the two equation, using the elimination method, we have,

$19-11 = 6a + b-(3.5a + b)\\8 = 2.5a\\\\\Rightarrow a = \dfrac{16}{5}\\\\11 = 6(\dfrac{16}{5}) + b\\\\\Rightarrow b = \dfrac{1}{5}$

Thus, the linear relationship is given by:

$R = \dfrac{16}{5}t + \dfrac{1}{5}$

where R is the R-value and t is the thickness in inches.
