Answer:
F' = (7, 6)
R' = (-1, 7)
I' = (-2, -5)
O' = (6, -6)
Step-by-step explanation:
The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.
Since it is shown that 2 of the sides of the triangle are congruent, we can assume that they have the same angle measures.
so to solve for the missing angle you can set up an equation equal to 180 since all triangles add up to 180 degrees.
21 + 21 + x = 180
42 + x = 180
x = 138
the value of the missing angle should be 138 degrees
hope this helped
x = 8, --- 12
I hope this helped :))))))))))))))))))
Answer:
She read 34% of the chapter
Step-by-step explanation:
You divide 17 by 50 and that gives you your answer
17/50=.34
move the decimal point 2 places to the right and the gives you your precent
.34=34%
10 would be called the Minuend.
4 would be called the Subtrahend.
4 would be the Difference.
