If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2
Fill in the point that it has to pass through on y and x
1=-1/2(0) + b
1=0+b
1=b
Then go back to the standard form y=mx + b and fill in the slope and y intercept
Y= -1/2x + 1
Sin = Opposite/ Hypotenuse
Sin (theta)= 5/10
Sin^-1(5/10)=30
theta=30
I think the question is wrong!
It must be
x-4
___= 5
x+2
Answer: x - 4= 5x + 10
or,-10 -4 = 5x - x
or, -14=4x
or,-14/4= x
Therefore, x = -14/4
Answer:
For b), the answer is 105mm
Step-by-step explanation:
(150+60)/2
Answer:

Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

solve for x


Find the angle measurements
