Answer:
25 degrees
Step-by-step explanation:
The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees. Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.
x is 25 degrees.
This is based upon the "corresponding angles" principle. Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.
Answer: 21
Step-by-step explanation:
SOLUTION:
If you drive at 55 mi/h for 110 miles, this means you drovefor 110 / 55 = 2 hours
Your total driving time is 4 hours and 15 minutes which meansthat you drove 2 and 15 minutes at the rate of 35 mi/h
2 hours and 15 minutes = 2×60 + 15 = 135minutes
35 miles / 60 minutes × ( 135 minutes) = 78.75miles
So total miles driven is 78.75 + 110 =188.75 miles
Answer:
6) 40°
7) 65°
8) 65°
Step-by-step explanation:
6) Total angle in a triangle is 180
180-70-70 = 40
7) y + 55 + 60 = 180
y = 65
8) 50 + n + n = 180
50 + 2n = 180
2n = 180 - 50
2n = 130
n = 130/2 = 65
