Answer:
x = 
y = 
Step-by-step explanation:
Hello!
This is a right isosceles triangle (45°-45°-90°). You can solve for the missing angle by simply subtracting 45° and 90° from 180° (sum of angles in a triangle equals 180°)
Since the triangle is isosceles, x and y are congruent because they are the legs opposite to the congruent angles.
In a right isosceles triangle, the hypotenuse is always the measure of one leg multiplied by
.
So, let's use leg y, 
Solve for y:

y =
, which means that x is also 
I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
Answer:
M= 1/2(x)+7
Step-by-step explanation:
Let M = Martha.
Let X = Number of Lucy's blocks.
Martha has half the amount as Lucy - 1/2(x)
Then 7 more than that - 1/2 (x) + 7
B 6x - 3

3/4 of flowers are tulips.
Of the tulips 2/3 are yellow.
= 2/3 of the 3/4 of all the flowers
= (2/3) * (3/4)
= 1/2 of all the flowers are yellow tulips.
