Answer:
x=20
Step-by-step explanation:
we know that
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa
In this problem
(x+16)° and (2x+14)° are complementary
That means----> the sum is equal to 90 degrees
so
[tex](x+16)^o+(2x+14)^o=90^o[/tex]
solve for x
[tex]3x+30=90\\3x=90-30\\3x=60\\x=20[/tex]
