Answer:
20
Step-by-step explanation:
<em>5+5+5+5</em>
(m^3)^-1 (x^2)^5 = (m^-3) (x^10) = x^10 / m^3
Step-by-step explanation:
A-B
=7x-6x/2 +10) - (-2x +6x-4)
=x/2+10- 4x+4
= x-8x /2 +14
=-7x/2+14
Hi there! :)

Recall that the sum of all angles in a triangle = 180°.
Therefore:
34° + 24° + x° = 180°
Combine like terms and subtract:
58° + x° = 180°
x = 180° - 58°
x = 122°
