Answer this question pls I need it rn

Answer:

K = 84°

L ; M = 48 ; 48

Step-by-step explanation:

L = (5x + 18)

M = (3x + 30)

K = k

L + M + K = 180° (sum of angles in a triangle)

The two base angles are equal :

Hence ;

5x + 18 = 3x + 30

5x - 3x = 30 - 18

2x = 12

x = 6

Hence,

L = 5x + 18 = 5(6) + 18 = 30 + 18 = 48°

M = 3x + 30 = 3(6) + 30 = 48°

K = 180 - (48 + 48)

K = 180 - 96

K = 84°

Laura retired from her job recently, and she has saved about $396,460.00 over the course of her career. She plans to withdraw $1
Tomtit [17]
So she has 396460
she will withdarw 1700 per month, and withdraw is loss or minus or (-)

after x months, she has 359060 left so

total-withdrawn=remaining
withdrawwn=1700 times months so withdrawn=1700x
total-1700x=remaining
total=396460
reaining=359060
subsitute
isolate x then divide is the strategy

396460-1700x=359060
add 1700x to both sides
396460=359060+1700x
subtract 359060 from both sides
37400=1700x
divide both sides by 1700
22=x

she has been retired for 22 months
