Combine like terms, find greatest common factors, and reduce fractions
Answer:
height is 4ft.
Step-by-step explanation:
I used pathagorus theorem .All explaination is in the pic below.
12/16, 7/16, 10/16 (not simplified, just with LCD);The LCD of the 3 fractions is 16 (from denominators) so all we have to do is multiply both the numerator by the same number that multiplies with the denominators to get 16. We leave 7/16 alone since it already has denominator of 16.
3/4 * 4 = 12/16
5/8 * 2 = 10/16
The Question is Incomplete The complete question with figure is below.
Answer:
Therefore the equation to solve for b is
![\tan 30 = \dfrac{5}{b}](https://tex.z-dn.net/?f=%5Ctan%2030%20%3D%20%5Cdfrac%7B5%7D%7Bb%7D)
Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠C = 90°
BC = 5 cm
AB = 10 cm
∠A = 30°
To Find:
b = ?
Solution:
In Right Angle Triangle ABC Tangent identity we have
![\tan A = \dfrac{\textrm{side opposite to angle A}}{\textrm{side adjacent to angle A}}](https://tex.z-dn.net/?f=%5Ctan%20A%20%3D%20%5Cdfrac%7B%5Ctextrm%7Bside%20opposite%20to%20angle%20A%7D%7D%7B%5Ctextrm%7Bside%20adjacent%20to%20angle%20A%7D%7D)
Substituting the values we get
![\tan 30 = \dfrac{BC}{AC}\\\\\tan 30 = \dfrac{5}{b}](https://tex.z-dn.net/?f=%5Ctan%2030%20%3D%20%5Cdfrac%7BBC%7D%7BAC%7D%5C%5C%5C%5C%5Ctan%2030%20%3D%20%5Cdfrac%7B5%7D%7Bb%7D)
Therefore the equation to solve for b is
![\tan 30 = \dfrac{5}{b}](https://tex.z-dn.net/?f=%5Ctan%2030%20%3D%20%5Cdfrac%7B5%7D%7Bb%7D)
