Solve for A please :)

a = 54 deg

Step-by-step explanation:

Recall that for a triangle, any exterior angle equals the sum of its two remote interior angles (see attached for reference).

In our case the exterior angle is 2a and the remote interior angles are (a+10) and 44

hence,

2a = (a+10) + 44

2a = a + 10 + 44

2a = a + 54   (subtract a from both sides)

2a - a = 54

a = 54 deg

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
