Answer:

h = 7.832

Step-by-step explanation:

This is a right angled triangle so, taking 50 as reference angle,

hypotenuse = ?

perpendicular = 6

The ratio for p and h is given by

Sin 50 = p/h

Sin 50 = 6 /h

h = 6 / Sin 50

h = 7.832

9 Given: p + q = 25. r + s = 25. q = r. Prove: p=s

MrRissso [65]

This is about simultaneous equations.

<u><em>p = s has been proved below. </em></u>

We are given;

p + q = 25 - - - (eq 1)

r + s = 25 - - - (eq 2)

q = r - - - (eq 3)

Let's put r for q in eq 1 to get;

p + r = 25 - - -(eq 4)

Let's subtract eq 2 from eq 4;

(p + r) - (r + s) = 25 - 25

p + r - r - s = 0

p - s = 0

p = s

A circular plate has circumference 16.3 inches. What is the area of this plate? Use 3.14 for pi.

serg [7]

Answer:

C = 2πr = 16.3

2(3.14)r = 16.3

r = 16.3/6.28

r = 2.5955414

Area: A = πr2

A = 3.14(2.5955414)2

A = 21.15366242 $in^{2}$

Step-by-step explanation:

The answer would be 21.2 $in^{2}$
