8/21 is the answer to the question
When we solve for y, we want to isolate y by itself. To do so in this equation, we can divide both sides of the equation by 62...
y = 434/62 = 7
Answer:
you can name it a or b like any letters
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
