Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.
Step-by-step explanation:
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.
Answer:
Real numbers
Step-by-step explanation:
When we draw the terminal side in a Cartesian plane, this side is located at quadrant 1. We have to solve angle theta in order to obtain the trigonometric functions. First, we solve the angle in the triangle formed of the terminal side.
tan alpha = 3/8
alpha = 20.56°
theta = 180° - 20.56° = 159.44°
<span>sin theta =0.35
csc theta =2.85
<span>cot theta = -8/3</span></span>
At least 30 more is likely to say yes to attending the school play, so it’s close to half and half
The nearest hundred will be in the hundredth place
For example, 2000
2 is in the thousands, followed by hundreds, ten, ones
to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.
So in this case 678 will equal 700
Example: if it were 644, then it would be 600
hope this helps
