This is the Pythagorean theorem where the 2 legs of a triangle squared add up to equal the squared hypotenuse (a^2 + b^2 = c^2)
The equation would be
12^2 + 5^2 = x^2
144 + 25 = 169
The square root of 169 = 13
Answer - 13 ft
Answer:
x = 30°
The angles:
- 2x° = 60°
- 3x° = 90°
- x° = 30°
Step-by-step explanation:
Hello!
The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.
Solve the equation:
- 2x° + 3x° + x° = 180°
- 6x° = 180°
- x° = 30°
We can replace 30° for all the angles.
The measures are:
- 2(30°) = 60°
- 3(30°) = 90°
- 1(30°) = 30°
Răspuns:
7/5;
2 întreg 5/12
Explicație pas cu pas:
6/7 × (2 numere întregi și 5 / 6-1 numere întregi și 1/5)
6/7 * (2 5/6 - 1 1/5)
6/7 * (17/6 - 6/5)
6/7 * (85 - 36) / 30
7/7 * 49/30
1/1 * 7/5
= 7/5
2.)
5/8 × 1 întreg și 2/3 + 11/5
5/8 * (1 2/3 + 11/5)
5/8 * (5/3 + 11/5)
5/8 * (25 + 33) / 15
5/8 * 58/15
1/8 * 58/3
= 58/24
= 2 întreg 10/24
= 2 întreg 5/12
Answer:
(6,-2.5)
Step-by-step explanation:
The formula for the midpoint between two points is:
Now we substitute
We have than (9, -1) is 
and (3, - 4) is 
So:
So, we have:
<h2>(6,-2.5)</h2><h2 />
I can do a graphic explanation if you want.
The answer to this is : 0.75 (.75)
