A+(−1.3)=−4.5
What does a equal.
Also what's your favorite song by Ariana Grande?

answer:

Step-by-step explanation:

Given that,

A+(−1.3)=−4.5

Note, +×-=-

Then,

A+(−1.3)=−4.5

A-1.3=-4.5

Add 1.3 to both side of the equation to remove the 1.3 from the left hand side of the equation.

A-1.3+1.3=-4.5+1.3

A=-3.2

The answer of A is -3.2

And for Ariana, I think I like her song with Nicki Minaj, bang bang.

angle addition postulate

2x=56

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
