Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x?
Allushta [10]

Answer:

1. 52° + x° + 67° = 180°

2.  x° + 22° = 90°

Step-by-step explanation:

1. In the first figure,

Since the angles given are supplementary angles i.e. their sum is 180°

So, we get,

52° + x° + 67° = 180°

i.e. x° = 180° - 119°

i.e. x° = 61°

Thus, the expression to find the value of x is 52° + x° + 67° = 180°.

2. In the second figure,

Since the angles given are complementary angles i.e. their sum is 90°

This gives us,

x° + 22° = 90°

i.e. x° = 90° - 22°

i.e. x° = 68°

Hence, the expression to find the value of x is x° + 22° = 90°

Licemer1 [7]

Answer:

g(x)= (x+8)^2 +2

Step-by-step explanation:

f(x) = x^2

We want to translate it 8 units to the left

h(x) = f(x+8)

h(x) = (x+8)^2

We also want to translate up 2 units

g(x) = h(x) +2

g(x)= (x+8)^2 +2
