Answer:
The measure of an arc is a degree or radian measure of how wide the arc is. Arc length is the length of the segment inside the arc on the circumference of the circle.
Step-by-step explanation:
The smallest angle of a right triangle whose legs measure 9 and 15 are F 31
Answer:
Largest angle is 105°
Smallest angle is 21°
The second angle is 54°
Step-by-step explanation:
Let the largest angle be x°
The smallest angle will be 1/5x°
The second angle will be x° - 51°
Angles in a triangle add up to 180° so;
x + x - 51 + 1/5x = 180
11/5x = 180 + 51 , 11/5x = 231 , x = 105°
Smallest angle is 1/5 × 105 = 21°
The second angle is 105 - 51 = 54°
Error is between steps 4 and 5. It should say:
Step 4: -9x < 27
Now divide by -9
Step 5: x > -3
Note that the inequality changes direction.
When you mean multiply or divide an inequality by a negative number, the inequality changes direction.
For example:
4 < 5
Multiply by -1:
-4 > -5
Another example:
-5 < 0
5 > 0
