Answer:
X=37/20
Explanation:
In a kite, one of the diagonals will bisect the other. So, 2(PT)=PR
By substitution, this becomes the equation
2(10x-1)=35
20x-2=35
20x=37
x=37/20

Answer:
Angle TQR is 52 degrees
Explanation:
A kite only bisects one set of opposite angles, so angle TQR is congruent to angle TQP. To find angle TQP use this equation:
Angle TPQ+Angle TQP=90
This is possible because angle QTP is right(diagonals of kites are perpendicular) and because all triangles have interior angles that add up to 180 degrees. The remaining amount of degrees apart from the right angle should be 90 degrees(180-90=90).
Substitute:
38+ angle TQP= 90
Angle TQP= 52 degrees
Angle TQP is congruent to angle TQR, so
Angle TQR=52 degrees
Answer:
-2
Step-by-step explanation:
look at 2 on the x axis and see where on the y does the line cross it
Answer:
The point slope form of this equation would be D) y - 8 = -3/7(x - 5)
Step-by-step explanation:
In order to find this, we simply plug in the information known into point-slope form, which is listed for you below.
y - y1 = m(x - x1)
y - 8 = -3/7(x - 5)
Answer:
The correct answer is (-5,-5)
Step-by-step explanation:
1. Both of the equations are in standard form, so first you set them equal to each other.
2. Solve for x as a normal algebraic equation.
3. Back substitute your answer for x into one of the original equations. (back substitution is just putting the x back into the equation and solving for y.)
4. Now you have your x and y coordinates, and the point of intersection of the two lines.
