How can I answer this question?

155⁰

Step-by-step explanation:

total angle in a triangle = 180

120 +35 =155

180-155=25

streight line =180⁰

180-25=155⁰

y=155

Step-by-step explanation:

Triangle = 180°

180°-120°-35° = 25°

Line = 180° - 25°

= 155°

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
