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
Question:- how many 50 cents coins are there in $10.50
Answer:-
Total amount-> $ 10.50
So amount in cents
$ 1 is equal to 100 cents
$10.50 is equal to 1050 cents
According to the question


Answer:
Step-by-step explanation:
Answer:
57 units^2
Step-by-step explanation:
First find the area of the triangle on the left
ABC
It has a base AC which is 9 units and a height of 3 units
A = 1/2 bh = 1/2 ( 9) *3 = 27/2 = 13.5
Then find the area of the triangle on the right
DE
It has a base AC which is 6 units and a height of 1 units
A = 1/2 bh = 1/2 ( 6) *1 = 3
Then find the area of the triangle on the top
It has a base AC which is 3 units and a height of 3 units
A = 1/2 bh = 1/2 ( 3) *3 = 9/2 = 4.5
Then find the area of the rectangular region
A = lw = 6*6 = 36
Add them together
13.5+3+4.5+36 =57 units^2
