Answer:
x = 109 degrees.
Step-by-step explanation:
The angle opposite the 45 degrees = 45 degrees (vertical angles)
Also the angle opposite to the 75 degree angle = 75 degrees for the same reason.
Now if we take the triangle on the left. the bottom right angle
180 - 75 - 45 = 60 degrees ( because the angles in a triangle sum to 189 degrees.
Next we find the left bottom angle of the triangle on the right.
This is 180 - 60 - 79 = 41 degrees (because these 3 angles are on the same straight line).
Finally x = 41 + 68 = 109 degrees ( external angle of a triangle theorem).
Answer:
17.9 degrees
Step-by-step explanation:
tangent x= 3.2/9.9
tangent x= 0.323
x=tan^-1(0.323)
x=17.9 degrees
Answer: $403.75
Step-by-step explanation:
Cost price= $475
Discount percent= 15%
Discount = 15% of 475
= 15/100 × 475
= 0.15 × 475
= $71.25
To get the reduced price of the keyboard, we subtract the discount from the cost price of the keyboard.
= Cost price - discount
= $475 - $71.25
= $403.75
The reduced price of the keyboard is $403.75
Answer:
Step-by-step explanation:
r = 4.9 miles
Area of circle = πr²
= 3.14 * 4.9 * 4.9
= 75.39 square miles
