Answer:
Adjacent, b = 45 units
Step-by-step explanation:
Let the length of sides of the triangle be;
- Opposite side = a
- Adjacent side = b
- Hypotenuse side = c
<u>Given the following data;</u>
Hypotenuse, c = 53 units
Opposite, a = 28 units
To find the missing side (adjacent), we would have to apply Pythagorean' theorem.
From Pythagorean theorem;
c² = a² + b²
Substituting into the formula, we have;
53² = 28² + b²
2809 = 784 + b²
Rearranging the equation (collecting like terms), we have;
b² = 2809 - 784
b² = 2025
Taking the square root of both sides, we have;
b = √2025
<em>Adjacent, b = 45 units</em>
You would need 16 because 3 × 4 = 12 and you need to do the same to the blue so you would do the equation 4 × 4 = ? which is 16.
Answer:
3.125
Step-by-step explanation:
Add 1.99 + 2.99 + 3.99 + 3.89 = 12.86
12.86 / 4 = 3.125
You divide by 4 since there are 4 terms.
Hope this helps!!
