Answer:
Step-by-step explanation:
take angle U as reference angle
using sine rule
sin U=opposite /hypotenuse
sin U=42/42
sin U=1
sin 90=1
therefore angle U=90 degree
Answer:14
Step-by-step explanation:
We know that
[area of <span>Martha's bathroom]=5*7-----> 35 ft</span>²
[area of one tiles]=(1/4)²-----> 1/16 ft²
if 1 tile has area of--------------> 1/16 ft²
x tiles---------------------------> 35 ft²
x=35/(1/16)-----> x=35*16-----> x=560 tiles
the answer is
560 tiles
9q-8q=18
q=18 and this is the answer- it says I need twenty characters soooooo
Answer:
Length = 10
Step-by-step explanation:
Normally you would use
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
But the 2 y values are the same so y2 - y1 = 0.
d then becomes sqrt(x2 - x1)^2
d = (x2 - x1) because the square root of (x2 - x1)^2 is just (x2 - x1)
x2 = 7
x1 = -3
d = (7 - - 3) = 10
