The reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size. Note that the numerator of a fraction just tells you how many pieces you have of that size.
To find the area of a triangle, you need the formula . A= b*h divided by 2
Answer:
The rule for a line whose gradient is -4 and y-intercept = 8 is

Step-by-step explanation:
Equation of line slope intercept form is
------------- (1)
Where m is slope or gradient and b is y-intercept
<u>Here</u>

Substituting values in equation (1)

Angle m∠1 if formed by a tangent and secant intersecting outside of circle. The intercepted arcs are arc LK and arc JK.
Thus;
Angle formed by Tangent and secant
=1/2(DIFFERENCE of Intercepted Arcs)
m∠1=1/2(mJK-LK)
Answer: m∠1=1/2(mJK-KL)
1)when we know x+y=90* the sine of x is equal to cosine of y , so the solution of the first is 0.6 again!
