A way you should find the answer is to compose the shape. You find the area of the entire shape then subtract the unshaded area's area. The rectangle's area is 16*8=128. Each of the triangle's area in the corner are 2 (2*2/2). 2*4=8 and 128-8 is 120.
You can but It would just be the same point
Okay first you should subtract 8.50 from 61.60 because the delivery charge doesn't count. 61.60-8.50=53.1. now divide 53.1 by 2.95. 53.1÷2.95=18. Romeo ordered 18 roses for his girlfriend.
The answer to the question
Answer:
In triangle SHD and triangle STD.
[Side]
Since, a line is said to be perpendicular to another line if the two lines intersect at a right angle.
⇒
[leg] [Given]
Reflexive property states that the value is equal to itself.
[Leg] [Reflexive property]
HL(Hypotenuse-leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are the congruent triangles.
then, by HL theorem;
