kirill [66]3 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

Since AC = BC then ΔABC is isosceles with base angles

∠BAC =∠ABC, thus

3x + x = 70

4x = 70 ( divide both sides by 4 )

x = 17.5

----------------------------------------------------

∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence

y = 70 + x = 70 + 17.5 = 87.5

What happens to the value of the expression 70 - 3g as g increases
exis [7]

Answer:

It decreases

Step-by-step explanation:

Given the expression: 70-3g

  • When g=1, 70-3g=70-3(1)=70-3=67
  • When g=2, 70-3g=70-3(2)=70-6=64
  • When g=3, 70-3g=70-3(3)=70-9=61
  • When g=4, 70-3g=70-3(4)=70-12=58
  • When g=5, 70-3g=70-3(5)=70-3=55

From the above, notice that as g increases, the value of the expression decreases.
