Answer:

105 degrees

Step-by-step explanation:

If j and k are vertical, then they are equal. So, the first progression is to set both angles equal to each other.

3x+21=5x-35

and solve for x

21=2x-35

56=2x

x=28

then plug x back into either equation (since they are equal you just need to find one)

3(28)+21 = 105

So, the angle of k or j is 105 degrees.

k = 105

KengaRu [80]

Answer:

Step-by-step explanation:

Cross multiply on both sides

= (x + 1) (21) = 15(x + 3)

= 21x + 21 = 15x + 45

Bringing like terms on one side

21x - 15x = 45 - 21

= 6x = 24

x = 24/6 = 4

Option A is the correct answer

Answer:

≈ 3.16 units

Step-by-step explanation:

To determine the distance between the two points, we need to use the distance formula. The distance formula states that;

$\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$

Given coordinates;

(6, -5)
(5, -8)

When we substitute the coordinates into the formula, we get;

$\implies \sqrt{[5 - 6]^{2} + [-8 - (-5)]^{2} }$

When we simplify the root, we get;

$\implies \sqrt{[-1]^{2} + [-8 + 5]^{2} }$
$\implies \sqrt{[-1]^{2} + [-3]^{2} }$
$\implies \sqrt{1 +9 }$
$\implies \sqrt{10}$ units ≈ 3.16 units (Using calculator)

Therefore, the distance between the points is about 3.16 units.

On his math test, Balavan wrote that a four-sided polygon that has at least two right angles must be a rectangle or a square. De

gregori [183]

A quadrilateral with only 2 right angles could be a trapezoid so Balavan is wrong. Denna is right because if 3 angles are right angles the the fourth angle must also be a right angle and has to be a square or rectangle.
