Answer:

(3, -2) is not a solution to 3x + 2y = -5

Step-by-step explanation:

Step 1: Check if solution by plugging in 3 for x and -2 for y

3(3) + 2(-2)

9 - 4 = 5

Step 2: Determine if true

3x + 2y = -5

5 = -5

NOT TRUE

Answer: (3, -2) is not a solution to 3x + 2y = -5

Tan 25.5 = h/x

Tan 20.5 = h / x+1

x tan 25.5 = (x+1) tan 20.5

x 0.476975532 = (x+1) 0.373884679

0.476975532x = 0.373884679x + 0.373884679

Deduct both sides by .373884679

0.103090853x = 0.373884679

x = 3.6267 is the first person.

Add one to get for the second person

X = 4.6267

If angle PQR and angle RQS form a linear pair and angle PQR =5x+5 and angle RQS =11x-65 then angle PQR=?

Mama L [17]

Answer:

m<PQR = 80°

Step-by-step explanation:

Points to remember

Sum angles in a linear pair is 180

To find the value of x

It is given that, angle PQR and angle RQS are linear pairs, and

m< PQR =5x+5 and m<RQS =11x-65

m<PQR + m<RQS = 180

5x + 5 + 11x - 65 = 180

16x -60 = 180

16x = 180 + 60

16x = 240

x = 15

To find the value of angle PQR

m<PQR = 5x + 5

= 5*15 + 5

= 75 + 5 = 80

Therefore m<PQR = 80°
