Step-by-step explanation:
sin 0 = opposite ÷ hypothenus
sin 0 = 3 / 5
3 / 5 = x / 15
5 × n = 15
n = 3
x = 3 × 3 = 9
y = use pythagoras
= 12
tan 0 = opposite ÷ adjacent
tan 0 = 9/12
Answer: B 163 degrees
Step-by-step explanation:
That's an obtuse angle, bigger than 90 degrees, so we read the appropriate upper scale for the angle.
11 and 11/15 is the answer
A should be the right answer because 4*5/4=5 + 5*2=10 and 5+10=15.
Answer:
in a triangle the angles have to measure to 180 degrees.
62 + 90 (right angle Q) =152
180 - 152 = 28
Angle S = 28
