X= 11 Y= 7 Z= 55

Step-by-step explanation:

125+ z= 180. Z= 55.

55+ (8x+37) =180. —> 92 +8x = 180. Subtract 92 from both sides. 8x = 88. Divide both sides by 8. X =11. 8(11) + 37 = 125 for that angle. Then 125+(6y+13) = 180 —>138 + 6y = 180. Subtract 138 from both sides. 6y= 42. Divide both sides by 6. Y = 7

It should be:

X=11

Y=7

Z=55

Step-by-step explanation:

8x+37=125, 125 - 27 = 88 / 8x = 11

6y+13=z : 180-125 = z {55}

6y+13=55, 55-13 = 42 / 6y = 7

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
