Answer:
A: 11,13, 290
B: 7,24,25
Step-by-step explanation:
A &B both form a right triangle not C
I believe that it is 30° if you round it to the nearest 10 but if it is to the nearest hundredth I think its 100?
<h2>
Similar Triangles</h2>
Similar triangles have the same proportions of sides, but they have different side lengths.
To solve for missing sides in similar triangles, we can set up a proportion.
For instance, let's say that side <em>a</em> in Triangle A corresponds with side <em>b</em> in Triangle B. Let's say that side <em>h</em> in Triangle A also corresponds with side <em>k</em> in Triangle B. Then, it would be true that:
We need to make sure of a couple things:
- The numerators and denominators of fractions are corresponding
- The numerators describe one triangle, and the denominators describe another (can't switch, otherwise the calculations will get messed up)
<h2>Solving the Question</h2>
We're given two triangles (do you see it?).
These two triangles are similar.
We must solve for the length of side BC in Triangle ABC.
- We're given the length of DE, the corresponding side in Triangle ADE.
- We're also given the lengths of bottom sides, 20 units and 30 + 20 = 50 units.
Set up a proportion:
Therefore, the unknown length is 37.5 units.
<h2>Answer</h2>
37.5 units
Answer: -s² - 3s + 6
Step-by-step explanation:
b = 1 - 2s² - s
c = 3 + 5s²
Substitute
3b + c
3 (1 - 2s² - s) + 3 + 5s²
3 - 6s² - 3s + 3 + 5s²
Put like terms together
-6s² + 5s² - 3s + 3 + 3
-s² - 3s + 6
Hope I helped!
Answer: 8 units
Step-by-step explanation:
This can be solved using the Pythagorean Theorem:
c² = a² + b²
c is the hypotenuse
a and b are the sides
Solving for the length:
10² = 6² + b²
100 = 36 + b²
b² = 100 - 36
b² = 64
b = √64
b = 8 units
The missing side is <u>8 units. </u>
