One way is to make into fracitons and simplify
A.5/7=25/35?
yes, true
B. 6/9=18/36?
no
C. 9/18=16/36?
no
D. 35/120=75/250?
no
another way is
if a/b=c/d, then (ad)/(bc)=1 or ad=bc
A is answer
Answer:
I think I might be terribly wrong but 160,728 ft
Step-by-step explanation:
THIS IS A RIGHT & isosceles triangle: A = 90. B = 45 THEN ANGLE C =45
THEN AB = AC = 4√2
APPLY PYTHAGORAS: BC² =AB² + AC²
===> X² = (4√2)² + (4√2)² ==>16.2 +16.2 = 64
X² 64 & X =√64 ==> X = 8
Answer/Step-by-step explanation:
Let's use Pythagorean theorem:
Formula : a² + b² = c²
Note that:
a is the long leg of the triangle
b is the short leg of the triangle
c is the hypotenuse
Side lengths Given are; 3 inches, 4 inches, 5 inches of a right triangle.
Hence,
a = 4 inches
b = 3 inches
c = 5 inches
Thus,
4² + 3² = 5²
16 + 9 = 25
25 = 25 [True]
