Answer:
Y= 30
Step-by-step explanation:
180-70=110 So now you know what your other two angles add up to.
Take 110 and your two other problems (3y-20) and (y+10)
Substitute y for a random number, as in 30.
Do the math (3(30)-20)
90-20=70 [Now your previous 110 is 40}
Then for the second equation (30+10)= 40
Y=30
Answer:
Step-by-step explanation:
Hypotenus=6
Adjacent=4
H and A
Cos x degrees= A divided by H
4 divided by 6=0.666666666
cos inverse(0.6666666666666666)
=48.2
=48
Answer:
-57
Step-by-step explanation:
3r x 6-11r x 5-20r x 1 any expression multiplied by 1 remains the same always calculate the product.
multiply calculate
18r-55r-20r
collect like terms
-57
This should be the answer if not let me know
