Find the value of x <br> 76degrees and 49degrees
Temka [501]

Answer:

Step-by-step explanation:

Judging by the context, you are looking for the angle x of a triangle, where the other two angles are 76 and 49. The sum of a triangle's angles is always 180, so

76 + 49 + x = 180

125 + x = 180

x = 55

The perimeter of a rectangle is 70. The length of the rectangle is represented by (x+3) and the width is represented by (3x-8).
otez555 [7]

Answer: length = 13

Width = 22

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length × width)

The length of the rectangle is represented by (x+3) and the width is represented by (3x-8). If the perimeter of a rectangle is 70, it means that

2[(3x - 8) + (x + 3)] = 70

Dividing both sides of the equation by 2, it becomes

3x - 8 + x + 3 = 35

3x + x - 8 + 3 = 35

4x - 5 = 35

4x = 35 + 5 = 40

x = 40/4

x = 10

Length = x + 3 = 10 + 3

Length = 13

Width = 3x - 8 = 3 × 10 - 8

Width = 22

The height of a triangle is 4 m less than its base. the area of the triangle is 48m^2 what is thr length of the base
romanna [79]
Base = x
height = x-4
Area = .5 * height * base
48 = .5 * (x-4) * x
96 = x^2 -4x
x^2 -4x -96=0
x = 12
base = 12
height = 8
