Use the properties of vertical angles to find the value of x. A)3
B)5
C)7
D)9

What is the measure of ∠A?
A)157°
B)159°
C)161°
D)163°​

The value of x= 7 and that of Angle A= 157°

Step-by-step explanation:

(x+16)° = (4x-5)° [Vertically opposite angles]

3x= 21

x= 7

Now, A + (4x-5)° = 180° [Linear pair]

A + [4(7)-5] = 180°

A + 23 = 180°

A = 180° - 23

A = 157°

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
