Question

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

93° (to the nearest degree)

Explanation:

sum of the interior angles of a triangle = 180°

Find angle C first, then subtract angle C and angle B from 180° to find angle A.

Use the sine rule
`(sinA)/(a)=(sinB)/(b)=(sinC)/(c)` to find angle C:

Therefore,

`(sinB)/(b)=(sinC)/(c)`

`(sin38)/(9)=(sinC)/(11)`

angle C = 48.80523914...°

Angle A = 180 - 38 - 48.80523914...°

= 93.19476086..°

= 93° (to the nearest degree)
