Answer:
Right angles is 90° so 90°+30°=120°.A straight line is 180°. So you do 180°-120° which is 60. So A=60°
D. The set of all points in a plane that are equidistant from a fixed point.
Answer:
x = 5
Step-by-step explanation:
To find the value of x make sure to get it on one side
First subtract 3x from each side. This makes the equation now
3x + 2 = -8 + 25
Now see what 25 subtract by 8 is (17)
3x + 2 = 17
Next subtract 2 from both sides
3x = 15
Lastly, divide 15 by 3, making x equal 5
x = 5
5)
3 decimals are

- 5.7
7)
3 decimals are
-3.18
-3.12
-3.05
That's a right triangle with hypotenuse 3000 and the height y is the side opposite the elevation angle of 15 degrees.
We can actually compute
exactly but I won't bother.
