The two equations that can be used to find the height are as follows:
- 12 / 4 = h /5
- 5 / 4 = h / 12
<h3>Similar Triangles</h3>
Similar triangles are not necessarily the same in size. Corresponding angles of similar triangles are congruent. The sides of similar triangle are a ratio of each other.
The tree cast a shadow of 12 ft. Let's establish the proportion base on similar triangles. The height of the tree is h. Therefore,
Therefore,
h / 12 = 5 / 4
cross multiply
4h = 60
divide both sides by 4
h = 60 / 4
h = 15 ft
Therefore, the two equations that can be used to find the height are as follows:
- 12 / 4 = h /5
- 5 / 4 = h / 12

Answer:
X=8
Step-by-step explanation:
RS + ST = RT
The equation is:
2 x + 10 + x - 4 = 21
3 x + 6 = 21
3 x = 21 - 6
3 x = 15
x = 15 : 3
x = 5
RS = 2 * 5 + 10 = 10 + 10 = 20
ST = 5 - 4 = 1
Answer: Segment RS = 20 and ST = 1

Answer:
b =28.28
Step-by-step explanation:
SinA/x = sinB/x
Sin30°/20=sin45°/b
Cross multiplication
20×sin45=b×sin30
20×sin45/sin30 =b
b=28.28
