Right triangle 45 45 90
so b = 2√2
and
a^2 = (2√2)^2 + (2√2)^2
a^2 = 8 + 8
a^2 = 16
a = 4
A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
Angle P is 50 degrees
OP is 17cm
They are similar quadrilaterals so their corresponding parts are congruent.
D. Becaus it is the only one that mentions the characters of a triangle
