Write (5,-3) and (10,-18) in standard form

Lelu [443]

Answer:

y = - $\frac{3}{4}$ x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

3x + 4y = 8 ( subtract 3x from both sides )

4y = - 3x + 8 ( divide all terms by 4 )

y = - $\frac{3}{4}$ x + 2 ← in slope- intercept form

Triangle A B C is shown. Angle C A B is a right angle. Angle A B C is 30 degrees and angle B C A is 60 degrees. The length of A

marishachu [46]

Answer:

i. sin(C) = $\frac{\sqrt{3} }{2}$

ii. tan(C) = $\sqrt{3}$

iii. sin(B) = $\frac{1}{2}$

Step-by-step explanation:

Given a right angled triangle ABC, with a right angle at A.

<ABC = $30^{0}$

<BCA = $60^{0}$

AC = 9 = 1

CB = 18 = 2

Applying Pythagoras theorem to ΔABC, we have;

AB = $\sqrt{BC^{2} - AC^{2} }$

= $\sqrt{2^{2} - 1^{2} }$

= $\sqrt{3}$

Thus applying the trigonometric ratios, it would be observed that;

i. sin(C) = $\frac{\sqrt{3} }{2}$

ii. tan(C) = $\sqrt{3}$

iii. sin(B) = $\frac{1}{2}$
