3/4 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (4)(12)
3x = 48
x = 48/3
x = 16
now notice this.....12/16 reduces to 3/4....probability's are nothing but equivalent fractions
Answer:
i think it might be the first or third one
Step-by-step explanation:
Answer:
BE = 49
Step-by-step explanation:
In triangle BDC
65^2=56^2+BD^2
65^2-56^2=BD^2
4225-3136=BD^2
1089=BD^2
33=BD
In triangle FDE
65^2=63^2+DE^2
4225-3969=DE^2
256 = DE^2
16=DE
since ED+DB=BE
THEREFORE
16+33=BE
49=BE
For the blue picture, use Pythagorean theorem. So 8.7^2 + x^2 = 32^2. Now solve for x and that’ll give you the missing side
