Mathematics
1 answer:
Inga [223]3 years ago
4 0

Answer:

Step-by-step explanation:

Left Hand Side

Change to sin(theta) and cos(theta)

csc(theta) = 1/sin(theta)

cot(theta) = cos(theta)/sin(theta)

1/sin(theta) - cos(theta)/sin(theta)                   Put over Sin(theta) Common denominator

[1 - cos(theta)] / sin(theta)                                Multiply numerator and denominator by 1 + cos(theta)

(1 - cos(theta)(1 + cos(theta) ) / sin(thata)*(1 + cos(theta))

(1 + cos(theta)(1 - cos(theta)) = 1 - cos^2(theta)

sin^2(theta) / (sin(theta)* ( 1 + cos(theta)

sin(theta) / (1 + cos(theta) )

Right hand Side.

See Above.

Given: m∠9 = 50° and m∠5 = 42°. Find the m∠14. Just type the number of the answer in the answer box.
sergejj [24]

Answer:

<h2>138°</h2><h2 />

Step-by-step explanation:

∡5 = 42°

find: ∡ 14

mr Goodwill [35]
The original perimeter is 22 cm.

If both sides are doubled, the length would be 16 cm and the width would be 6 cm.
The perimeter would be 44 cm.

22/44 is 50%.
