Question

aiuda man no entiendo les doy coronita

Answer 1

1.-

$180° = 2 \alpha +14° + 10° + 26°$

$180° = 2 \alpha +50°$

$2 \alpha = 180° - 50°$

$2 \alpha = 130°$

$\alpha = \frac{130°}{2} = 65°$

2.-

$180° = 70° + 60° + a$

$180° - 130° = a$

$a = 50°$

3.-

$180°- 135°= \theta$

$\theta = 45°$

4.-

$180 - 140 = 40°$

$180° = 90° + 40° + \theta$

$\theta = 180° - 90° - 40°$

$\theta = 180° - 130°$

$\theta = 50°$
