Since the triangle is a right triangle at point B, then line AB is perpendicular to line BC.
For perpendicular lines, the product of their slopes is -1.
Slope of AB = (5 - 0)/(2 - 5) = 5/-3 = -5/3
Slope of BC = (y - 5)/(7 - 2) = (y - 5)/5
-5/3(y - 5)/5 = -1
-5(y - 5)/15 = -1
-5(y - 5) = -15
y - 5 = 3
y = 3 + 5 = 8
Therefore, the y-coordinate of point C is 8.
Answer:
d + 6
Step-by-step explanation:
Given that :
Number of dogs = d
The sum of the number of the number of dogs and 6 cats is :
This is a straightforward question :
We take the sum of d and 6
Hence, we have
d + 6
Answer:
x ≈ 57.8°
Step-by-step explanation:
using the Sine rule in the triangle
= 
( cross- multiply )
8 × sinx = 11 × sin38° ( divide both sides by 8 )
sinx = 
, then
x = 
( ) ≈ 57.8° ( to 1 dec. place )
The answer is D.
120 divided by 24 would not give you the price of ONE pen
Two -2x and 2x cancel out since there opposites
As well as y
Then your answer should be 0=-1
