Answer:

R= {-7,-2}

Step-by-step explanation:

divide 14 into 2 and 7 because 2x7=14
write the equation as a multiplication of (x+7) and(x+2) =0
for the result to equal zero. at least one of the factors must equal zero, therefore we get two solutions

i think it will make it smaller due to the base being longer which stretches out the two sides and makes less space inside of the triangle

Given:

A right angled triangle.

To find:

The value of x.

Solution:

We have,

Base = x

Hypotenuse = $\sqrt{5}$

In a right angle triangle,

$\cos \theta = \dfrac{Base}{Hypotenuse}$

For the given triangle,

$\cos 45^\circ= \dfrac{x}{\sqrt{5}}$

$\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}$

Multiply both sides by $\sqrt{5}$ .

$\dfrac{\sqrt{5}}{\sqrt{2}}= x$

$\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x$

$\dfrac{\sqrt{10}}{2}= x$

Therefore, the required value of x is $\dfrac{\sqrt{10}}{2}$ .

10 x 13 x 11 = 1430

10 x 5 x 6 = 300

1430 + 300 = 1730
