Can anyone explain please?
frosja888 [35]

Answer:

x = 55

Step-by-step explanation:

In a rhombus, each diagonal bisects a pair of opposite angles.

For this parallelogram t be a rhombus, the angles with measures 2x - 40 and x + 15 must be congruent.

2x - 40 = x + 15

Subtract x from both sides.

x - 40 = 15

Add 40 to both sides.

x = 55

What is the slope of a line that is perpendicular to the line y = x + 4? The slope of the line is ______?
serg [7]
Slopes of perpendicular lines are opposite reciprocals of each other. The slope of the given equation (which is in slope-intercept form) is 1, the invisible coefficient of x. The opposite reciprocal of 1 is -1, thus the slope of a line perpendicular to the line y = x + 4 is -1.

Hope this helps.

Find the distance between these points.<br> R(-1,0), S(8,6)<br> V(26)<br> V(85)<br> 3V(13)
Thepotemich [5.8K]

Answer:

The distance is equal to 3\sqrt{13}\ units

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

R(-1,0)\\S(8,6)  

substitute the values

d=\sqrt{(6-0)^{2}+(8+1)^{2}}

d=\sqrt{(6)^{2}+(9)^{2}}

d=\sqrt{36+81}

d=\sqrt{117}\ units

Simplify

d=3\sqrt{13}\ units
