Answer:
35
Step-by-step explanation:
A=1/2(b_1+b_2)h
A=1/2(4+10)5
A=1/2*70
A=35

i... um.... ok then
Step-by-step explanation:
Answer:
Please check the explanation.
Step-by-step explanation:
Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.
In other words,
P(x, y) → P'(-y, x)
From the given triangle ΔRST,
The coordinates of the point S is:
According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:
S(10, 1) → S'(-1, 10)
Here,
S'(-1, 10) is the image of the original point or pre-image point S(10, 1).
Therefore, the y-coordinate of the point S' is: 10
