Review the meaning of "straight angles."
Here 110 and A are "straight angles," and so 110 + A = 180 (degrees).
Then A = 70 degrees.
Answer:
A=1/2 bh
multipy 2 at both side of the equation
2A = bh
divide b at both side , then we will get h
h = 2A/b
Step-by-step explanation:
Answer:
Tags not given out=(k/5)-40
Step-by-step explanation:
k is tag
Tags k given to student are half = k/2
Tags given to parents are= 100
Total tags given to students and parents are=(k/2)+100
So remaining tags are=k-(k/2+100)
=(k-200)/2
tags given to judges and teacher are 3/5 of remaining tags =(3/5)*((k-200)/2)
So tags not given out are =(2/5)*((k-200)/2)
=(k/5)-40 Answer
