Find angle a if measurement of arc mde is equal to 70° and measurement of arc mbc is equal to 12°.

Angle A = 29°

Step-by-step explanation:

Remember one thing that when two secants intersect in the exterior of a circle then A=1/2(mDE-mBC) it means that the measure of the angle formed is one half the difference of the measures of the intercepted arcs

Now put the values in the equation.

A=1/2(mDE-mBC)

A=1/2(70-12)

A=1/2(58)

A = 29°

Thus angle A = 29° ....

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
