Answer:ΔSRT and ΔTRP
Step-by-step explanation:
We are given that R is a point on hypotenuse SP such that the segment RT is perpendicular to PS, therefore, PR=RS as the perpendicular bisector divides the line segment in two equal halves.
Now,
In ΔSRT and ΔTRP,
PR=SR( Since RT is perpendicular bisector, it divides PS in two equal halves)
∠PRT=∠SRT=90° (RT is perpendicular bisector of PS)
RT=RT(Common)
Therefore, by SAS rule of congruency,
ΔSRT ≅ΔTRP
Hence, Option D is correct.
Answer:
49
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.Laura's design will be light enoughThe shape is given as a trapezium (see attachment).First, calculate the height (h) of the trapezium using the following Pythagoras theorem 52=h2+x2 Where: x=11−92=1 So, we have: 52=h2+x2 52=h2+1225=h2+1 Collect like terms h2=25−1 h2=24 Take square root sh=4.90The area of the shape is then calculated as follows: Area=12(11+9)×h Area=12(11+9)x4.90 Area=12×20×4.90 Area=10×4.90 Area=49
The area of the shape is 49 square inches.Hence, the shape will be light enough (because 49 is less than 80
The third one because it says 4 of 7 and the rest which is 3 eat a school meal
So the ratio is 4:3
