1.25 x 2 = ?
1/2 x 2 = 1 hour
? = 2.5
Step-by-step explanation:
the exterior angle at every interior angle will be found by 180 minus the interior because angles on a straight line add to 180 degrees
The sum of the exterior angles in a shape always add up to 350 degrees
Answer:
The value of x is 17
Step-by-step explanation:
The sum of the angles in a triangles is 180°
From the question:
In ΔVWX,
m∠V=(4x+3) ∘
m∠W=(x+7) ∘
m∠X=(5x+0) ∘ .
Hence:
m∠V + m∠W + m∠V = 180°
4x + 3 + x + 7 + 5x + 0 = 180°
Collect like terms
4x + x + 5x + 3 + 7 + 0 = 180°
10x + 10 = 180°
Subtract 10 from both sides
10x + 10 - 10 = 180° - 10
10x = 170
Divide both sides by 10
10x/10 = 170/10
x = 17
The value of x is 17
Answer:

Step-by-step explanation:
Let ∠4 be x then ∠6 is
x
∠4 and ∠6 are same side interior angles and are supplementary, thus
x +
x = 180
Multiply through by 8 to clear the fraction
8x + x = 1440, that is
9x = 1440 ( divide both sides by 9 )
x = 160
Hence ∠4 = 160° and ∠6 = 160° ÷ 8 = 20°
