Answer:
Tom weighs 70 pounds
Step-by-step explanation:
first, you have to set up your equation which would be, x + 3x = 280.
The x stands for Tom's weight and the 3x stands for three times Tom's weight for the dad. You would then add your like terms, then divide by 4 to get 70.
x + 3x = 280
4x = 280
280/4 = 70
x = 70
Hope this helps!
Answer:
63 degrees.
Step-by-step explanation:
TRaingle ABC is isosceles so the base angles are equal That is < BAC = < BCA.
<BAC = 180 - 117 = 63 degrees ( because it is adjacent to <x which is 63 degrees).
So < BCA = <BAC = 63 degrees.
Finally y = 63 degrees ( vertical angles are equal).
