Step-by-step explanation:
well you could estimate it or just add 2.5 to 6.9 and you would get pretty close to the answer
<u>Have a good day! :)</u>
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90°
in this problem
(x+21)+<span>(2x+21)=90-------> 3x+42=90-------> 3x=48-----> x=16</span>°
