Answer:

Below in bold,

Step-by-step explanation:

m < JIK = the sum of the measure of the other 2 angles so we have:

140 - 6x = 20x - 10 + 8x - 20

140 + 10 + 20 = 20x + 6x + 8x

170 = 34x

x = 5.

m < JIL = 20(5) - 10 = 90 degrees.

m < LIK = 8(5) - 20 = 20 degrees.

m < JIK = 140 -5(5) = 110 degrees.

6. 5x = 8x - 4 (as QB is the bisector of < AQC.

Solve for x then substitute the value of x as in question 5.

Mars2501 [29]

Step-by-step explanation:

180°=46° +2x=> 2x=134°=>x=67°

x+y=180°=>y=180° -x=>y= 180°-67°=>y=113°

The weight of a Great blue heron, a type of bird, can grow to around 4 pounds, but can vary. Let W be a random variable that rep

hammer [34]

Answer:

10 ≥ w ≥ 9 ( ? )

Step-by-step explanation:

the probability that a Great blue heron is at least 9 pounds, but no more than 10 pounds -> w= weight of great blue heron

w is at lest 9 pound's -> w ≥ 9

w is no more than 10 pound's -> w ≥ 10

w ≥ 9 ( + ) w ≥ 10 = 10 ≥ w ≥ 9

we do not know how much the price of a commodity is, but it has been reduced by 10% and now costs 20€. What was the starting pri

MrRissso [65]

I got 22 because if u do 20 multiplied by 10% that gives u 2 which u then add onto the 20 to get the starting price. 10% of 22 is 2 and then 22-2 = 20 (if u we’re doing it from the starting price)
