Statements are all TRUE

sinA = \frac{a}{c} and cosB = \frac{a}{c}


cscA = 1/sinA = 1/(a/c) = \frac{c}{a} and secB = 1/cosB = 1/(a/c) = \frac{c}{a}

tanA = \frac{a}{b} and cotB= 1/tanB = 1/ (b/a) = \frac{a}{b}

In the adjoining figure O is the centre of the circle the tangent to the circle of radius 6 cm from the exterior point P of the
slamgirl [31]

Answer:

Let P be the external point. O be the origin. join O and P get OP and nearest point on the circle from P be A.

Let Q be the point onthe circle  in which, tangent make 90° with radius at Q.

PQ = 8 and OQ = 6

we get a right angled triangle  PQO right angled at Q.

so, OP^2 = OQ^2 + PQ^2= 8^2 + 6^2 = 64 + 36 =1==

therefore OP =10cm

we need nearest point from P, which is PA

PA = OP - OA= 10 -6=4cm

Ksivusya [100]

Using proportions, it is found that Student 2 is correct, as 37.6/0.1 = 376.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

One tenth is worth 0.1. How many tenths are there in 37.6? The division is given as follows:

37.6/0.1 = 376.

Hence student 2 is correct, as there are 376 tenths in 37.6.
