Answer:
The measure of the largest angle is 72º.
Step-by-step explanation:
We will first solve for x. We know that the sum of the interior angles of a triangle is 180º, so 15x + 21x + 24x is equal to 180º. This means that 60x = 180º, so x = 3º. The largest angle is 24x, which is 72º.
Answer:
Yes she will reach her goal
Step-by-step explanation:
The total miles to be skated by Maribel on monday is 1 1/2 miles.
On Monday morning she skates 9/10miles
If on Monday afternoon she skates 8/9 of that distance on Monday, then she must have skate (8/9 of 9/10) miles in the afternoon which is equivalent to 4/5miles.
Total miles she skated will be 9/10+4/5 = 9+8/10
= 17/10
= 1 7/10 miles
This means that she will reach her goal and even pass the initial total miles she wanted to skate which is 1 1/2miles
No the 8/12 is the bigger one
Answer:
x = 4
Step-by-step explanation:
Given
4.5x = 18 ( divide both sides by 4.5 )
x = 4
Answer:
Step-by-step explanation:
Since we are given the central angle in radians, we should use this formula for the sector area:
where r is the radius and θ is the angle in radians.
The radius is 14 units and the angle is 7.2 radians.
Substitute the values into the formula.
Solve the exponent.
- (14 units)²= 14 units* 14 units =196 units²
Multiply by 1/2 or divide by 2.
The area of the sector is 705.6 square units.
