Answer:
Sec y = q/r
Step-by-step explanation:
Sin y = 7/q
tan y = 7/r
Mathematically cos y = sin y/tan y
But sec y = 1/cos y
So therefore sec y = tan y/sin y
So that would be ;
7/r divided by 7/q
= 7/r * q/7
= q/r
Parallel because they have the same slope
Answer:
16 3/10
Step-by-step explanation:
Think about what fraction become .3 when put into a calculator
that's a 3 in the tenths place in the decimal system so the fraction would be 3/10. Then finally add on the 16
*an aside if this is wrong it it is possible that they have rounded 1/3 to one decimal place. (1/3 is usually .33333 repeating)
Answer:
C
Step-by-step explanation:
From the given coordinates
A(6, 0), B(0, 0) then AB = 6 - 0 = 6
B(0, 0), C(0, 8) then BC = 8 - 0 = 8
To calculate AC use Pythagoras' theorem on the right triangle formed
AC² = AB² + BC² = 6² + 8² = 36 + 64 = 100
Take the square root of both sides, hence
AC =
= 10
Perimeter = AB + BC + AC = 6 + 8 + 10 = 24 → C
