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)
Answer:
(3^6)/2
Step-by-step explanation:
make sure everything as the numerator is in parenthesis
x = 2 and y= 1
y = 3x-5
1= 3 x 2 - 5
1= 6-5
1=1
6x+3y=15
6 x 2 + 3 x 1 = 15
12+3=15
15=15
