Answer:
y = 13.2 feets
Step-by-step explanation:
Difference implies minus...
y ft - 6.2 ft = 7ft
Add +6.2 ft to both sides
y ft - 6.2ft + 6.2ft = 7ft + 6.2 ft
y ft + 0 = 13.2ft
y = 13.2 ft
73 + 55 = 52 + n
Subtract 52 from each side:
73 + 3 = n
n = 76
Answer:
65º
Step-by-step explanation:
- The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
- The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
- We can solve from there, x+40+3x+10+180-6x=180
- Combine like terms, -2x+230=180
- Subtract 230, -2x=-50
- Divide by -2, x=25
- m∠CAB=(x+40)º=(25+40)º=65º
- m∠ABC=(180-6x)º=(180-150)º=30º
- m∠BCA=(3x+10)º=(75+10)º=85º
Answer:
1.67 hours
Step-by-step explanation:
Let the original speed of Jonathan =
units/hr
Let the original time taken by Jonathan =
hours
Let the distance =
units
Formula for distance is given as:

Given that half the distance is covered by original speed.

Half the distance is covered by increasing the rate by 25%.
i.e. increased speed:

Hence, Time taken:

Distance traveled is half of the total distance:

Dividing (1) by (2):

Answer:
č= 67°
Step-by-step explanation:
x + 78+35=180
x + 113=180
x= 180-113
x= 67 degrees
