Find the value of x.

m∠IHG = 162°

m∠IHK = (4x + 4)°

m∠KHG = (8x + 2)°

1

Step-by-step explanation:

<IHG = 162

<IHK = 4x + 4

<KHG = 8x + 2

<IHG + <IHK + <KHG = 180° (sum of angles in a triangle is equal to 180°)

See attachment for better illustration of the triangle

162 + (4x + 4) + (8x + 2) = 180

162 + 4x + 4 + 8x + 2 = 180

168 + 12x = 180

Collect liketerms

12x = 180 - 168

12x = 12

x = 1

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
