Step-by-step explanation:
$40+$16(that is, 8+8)=56 and 50+6=56
Answer:
x = 35°
Step-by-step explanation:
The question is as following
cos x = sin(20 + x)° and 0° < x < 90° , find X?
==============================================
cos x = sin(20 + x)°
sin and cos are co-functions,
which means that: cos x = cos [90 - (20 + x)]
∴ x = 70 - x
∴ 2x = 70
∴ x = 35°
======================
Note: cos θ = sin ( 90 - θ )
So you answer is B. i hope that this helps you and you have an amazing day!
