What is the value of u?<br> u+40°<br> U-19°<br> U=

Vlad1618 [11]

Answer:

u = 59

Step-by-step explanation:

The sum of the exterior angle is equal to the sum of the opposite interior angles

u+ u-19 = u+40

2u -19 = u+40

Subtract u from each side

2u-19-u = u+40-u

u-19 = 40

Add 19 to each side

u+19-19 =40+19

u = 59

The lengths of the diagonals of a rhombus are 2x and 10x. What expression gives the perimeter of the rhombus?

True [87]

Answer:

$P=4x\sqrt{26}\ units$

Step-by-step explanation:

we know that

The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other

Applying the Pythagorean Theorem

$c^2=a^2+b^2$

where

c is the length side of the rhombus

a and b are the semi-diagonals

we have

$a=2x/2=x\ units\\b=10x/2=5x\ units$

substitute the values

$c^2=x^2+(5x)^2$

$c^2=26x^2$

$c=x\sqrt{26}\ units$

To find out the perimeter of the rhombus multiply the length side by 4

$P=(4)(x\sqrt{26})$

$P=4x\sqrt{26}\ units$
