Answer:
- smallest: 18°
- largest: 90°
- middle: 72°
Step-by-step explanation:
We can solve this using the relationship between the angles together with the angle sum theorem. Let s represent the measure of the smallest angle. Then the middle angle is 4s, and the largest angle is (4s +s). The angle sum theorem tells us the sum of angles in a triangle is 180°.
smallest + middle + largest = 180°
s +(4s) +(4s +s) = 180°
10s = 180° . . . . . . . . . . . simplify
s = 18° . . . . . . . . . divide by 10
4s = 72° . . . . . . find the middle angle
4s +s = 72° +18° = 90° . . . . . find the largest angle
The smallest, largest, and middle angles are 18°, 90°, and 72°, respectively.
In order to match each of the pairs you need to divide the numerator by the denominator to make it into a decimal.
Below are the pairs:
21/25 = 84%
13/20 = 65%
2/5 = 40%
3/4 = 75%
3/5 = 60%
For this case we must find the value of "x" of the following expression:
Multiplying by 2 on both sides of the equation:
Subtracting 8x from both sides of the equation:
Adding 16 to both sides:
Dividing between -2 on both sides:
Answer:
Your absolute value cannot be negative.
Answer:
18:54
Step-by-step explanation:
We have to simplify these ratios.
If the most simplified form of the ratios are equal, they are equivalent
3:9
24:54
18:54
Same ratio as 3:9, so 18:54 is equivalent to 3:9
36:81
