Answer:
Step-by-step explanation:
If the ratio of triangle = 6:3:7
Total ratio = 6+3+7 = 16
The sum of angle in a triangle is 180°
1st angle= 6/16 × 180 = 6 × 11.25
= 67.5°
2nd angle= 3/16 × 180 = 3 × 11.25
= 33.75°
3rd angle= 7/16 × 180 = 7 × 11.25
= 78.75°
Largest is 78.75° and smallest is 33.75°
Answer:
y=-1/6x-13/3
Step-by-step explanation:
first we find the slope
y1-y2/x1-x2
-3+5/-8+4
1/-6
now we find y intersept
-3=-1/6(-8)+b
-3=8/6+b
-13/3=b
you plug it in y = mx+b
y=-1/6x-13/3
The temperature at the beginning of the day was 6.2°F
Let x represent the temperature at the beginning of the day.
Since, the temperature of a city doubles during the day, and then decreases by 14.1ºF after the sun goes down, hence:
Temperature at end of day = 2x - 14.1
Also, the temperature at the end of the day is −1.7°F, hence:
2x - 14.1 = -1.7
2x = 12.4
x = 6.2°F
The temperature at the beginning of the day was 6.2°F
