Answer:
Step-by-step explanation:
We have the equation:
we know that:
14*14 = 196
then:
14 = √196
Now, we can rewrite:
50 = 2*25
98 = 2*49
This is because we know that 49 and 25 are perfect squares, then:
Now we can use the common factor √2 and get:
and we know that:
7*7 = 49
5*5 = 25
then:
the value of b is:
b = 12
Answer:
190000
Step-by-step explanation:
Answer:
29 ft
Step-by-step explanation:
the screens have 90 degree angles so they form right triangles with the diagonal, so use Pythagorean theorem to solve for the diagonal
diagonal² = 21² +20² , square and square root both sides of the equation
diagonal = √441+400, add
diagonal = √841, square root
diagonal = 29ft
