The temperature in montreal was -8°c
in new york the temperature was 11°c
how many degrees warmer was the temperature in new york?

Temperature was 19 degree warmer in New York compare to temperature in Montreal.  

Solution:

Given information is as follows  

Temperature in Montreal = -8  

Temperature in New York = 11

Need to find by how much degree the temperature was warmer in New York.

degree by which temperature was warmer in New York compared to Temperature of Montreal is equal to (Temperature in New York) – (Temperature in Montreal)

= 11 – (-8)  = 11 + 8 = 19

Hence temperature was 19 degree warmer in New York compare to temperature in Montreal.  

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the correct option is b
