<7 = <5 (vertical angles)
<5 = <1 (corresponding angles)
so <7 = <1 = 135°
Answer
<7 = 135°
Answer:
1) 102/21
2) 21/51
3) 21/24
Step-by-step explanation:
Well you have to find the GCF. The GCF in this problem would be 4. So divide 92 and 100 by 4. 92/4 is 23 and 100/4 is 25. So 92/100 is 23/25 in lowest terms.
Here, we are required to find how many hours per week does Lindsey need to study if she wants to have an average of at least 90
Lindsey needs to study for at least 15.25 hours to have an average of 90
Given expression:
4(h + 11) – 15
Where,
h = number of hours
For Lindsay to have at least 90
4(h + 11) – 15 = 90
open parenthesis
4h + 44 - 15 = 90
4h + 29 = 90
4h = 90 - 29
4h = 61
Divide both sides by 4
h = 61/4
h = 15.25 hours
Therefore,
Lindsey needs to study for at least 15.25 hours to have an average of 90

Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
