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:
yes
Step-by-step explanation:
Girls:
12 girls out of 30
12/30
Divide the top and bottom by 6
2/5
Boys
16 out of 40
Divide the top and bottom by 8
2/5
8+6+1 =15
-a
-2b-3b =-5b
-3c
15-a-5b-3c is the answer
Answer:
17
Step-by-step explanation:
3(-2)^2 - 2(-2) + 1
