Answer:
24 and 21 are the two numbers
Step-by-step explanation:
let n represent the unknown number
let n-3 represent the second unknown number
n+n-3 = 45
2n-3=45
2n=45+3
2n=48
n=48/2
n=24
n-3=21
CHECK: 24+21=45
.˙. the first number is 24 and the second number with a difference of 3 is 21

Answer:
Step-by-step explanation:
Both of the triangles are special 30-60-90 triangles
and the side lenghts for these angle mesurements are followed : q, q√(3),2q
q is given as 3 from the 9th question
so a = 6 (because it's 2q) and
b = 3
For the 10th question
the side length that sees 30 degrees is 3 which means q = 3 again
and x = 6
y = 3√(3)
