Answer:
b. 1:3
Step-by-step explanation:
To find the hypotenuse of the first triangle, use a^2 + b^2 = c^2
c = sqrt (5^2 + 12^2)
c = 13
From here, since they are similar, you can set up a proportion
13:39
1:3
Answer:
The equation of the line is y = -1
Step-by-step explanation:
In order to find the equation,y = mx + c, you have to find the gradient first using the formula :
Let (x1,y1) = (-8,-1) & (x2,y2) = (-8,-1),
m = (-1)-(-1)/-8-(-8)
= 0
Now, we have found the gradient, next using the formula, y = mx + c to find the equation :
y = mx + c
Let m=0,
At (-8,-1)
-1 = 0(-8) + c
c = -1
y = -1
