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: A
a quadrilateral with all four angles right
Step-by-step explanation:
A quadrilateral is a rectangle if a quadrilateral has all four angles right,
a parallelogram with congruent sides
a quadrilateral with diagonals that are congruent and bisect each other
a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which
are parallel and congruent. And all its angles are congruent.
But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.
0.161 (they said explain it so)
(5) you need to subtract 19 from 25 or
9 plus x the number to get 14
