Answer:
C
Step-by-step explanation:
Sinፀ = opposite / hypotenuse
sinፀ = 12mm / 48mm
ፀ= Arcsin(12/48)
=16.7°
So my understanding from this you have to make it y = mx + b so m stands for the slope there’s different ways to find it as shown in the first picture. I’ll try to make another comment since this only lets me take one picture at a time.
Well 42 divided by 2 is 21. than to double check you can do 21 plus 21 equals 42.
I hope this helps you
10^2=5^2+x^2
100-25= x^2
x= 5 square root of 3
