Answer:

49 mm

Step-by-step explanation:

A scale factor is the number you multiply a side length by to find the image. This means we multiply MN, which is 28 mm, by the scale factor, 7/4:

28(7/4) = 196/4 = 49

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) = $\frac{1}{2}$
