Math PLEASE HELP IM SO CONFUSED IM ATTACHING THE SLIDES!!!!

slavikrds [6]

Answer:

x = 19, TS = 22

Step-by-step explanation:

Use ratios to solve for x. Corresponding sides have same ratio.

Q1

(x + 5)/30 = (36 - 20)/20
(x + 5)/30 = 16/20 = 4/5
5(x + 5) = 4(30)
5x + 25 = 120
5x = 95
x = 19

Q2

(5x - 2)/(3x + 1) = 39/26
(5x - 2)/(3x + 1) = 3/2
2(5x - 2) = 3(3x + 1)
10x - 4 = 9x + 3
10x - 9x = 3 + 4
x = 7

TS = 3x + 1 = 3(7) + 1 = 22

Question 6 of 15

umka2103 [35]

Answer:

$LE=5\ units$

Step-by-step explanation:

we know that

In a rectangle, the two diagonals are congruent and each diagonal bisects the other

so

$LN=2KE$ ----> equation A

$KE=LE$ -----> equation B

step 1

Find the value of x

solve equation A

$LN=2KE$

substitute the given values

$(2x+2)=2(3x-7)$

solve for x

$2x+2=6x-14\\6x-2x=2+14\\4x=16\\x=4$

step 2

Find the value of KE

$KE=3x-7$

substitute the value of x

$KE=3(4)-7=5\ units$

Remember that

$KE=LE$ -----> by each diagonal bisects the other

therefore

$LE=5\ units$
