In right triangle ABC, angle C = 90 degrees, c = 3, and a + b = square root of 17. Compute the area of the triangle.
Klio2033 [76]

Answer:

2

Step-by-step explanation:

Given in the question,

a + b = √17

(a+b)² = 17

a² + b² +2ab = 17

a² + b² = 17 - 2ab

<h3>Area of triangle </h3>

1/2 (h)(b)

here h is perpendicular height of triangle = a

        b is the base of triangle = b

<h3>Use pythagorus theorem:</h3>

hypotenuse² =  base² + height²

3² = a² + b²

9 = a² + b²

9 = 17 - 2ab

9 - 17 = -2ab

-8  = -2ab

cancel minus on both sides

8  = 2ab

ab = 8/2

ab = 4

Plug ab in the formula of area

1/2 (h)(b)

1/2 (a)(b)

1/2 (4)

4/2

What is the largest of three consecutive positive integers if the sum of the smaller two integers is 11
FromTheMoon [43]
Let, the numbers are: x, (x+1), (x+2)
Now, x+x+1 = 11
2x + 1 = 11
2x = 10
x = 5

So, largest number would be: (x+2) = (5+2) = 7

In short, Your Final answer would be 7

Hope this helps!

. Show that square of any positive integer can not be of form 7q + 3 or 7q+5or 7q + 6, for any integer q
Svetradugi [14.3K]

Step-by-step explanation:

7q + 3 or 7q+5 or 7q + 6

solve for q

7q + 3 =

7q + 3 -3 =-3

7q = -3

7q/7 = -3/7

q = -3/7

7q + 3 =

7q + 6 -6 =-6

7q = -6

7q/7 = -6/7

q = -6/7
