Question

Given the triangle below, answer the following:

Answer 1

Answer:

Step-by-step explanation:

question no . 5

ratio of angle L

take angle as reference angle

using cos rule

cos L = base / hypotenuse

= 4/5

ratio of angle N

take angle N as reference angle

using sin rule

sin N = opposite / hypotenuse

= 4/5

for measure of angle L

cos L = 4/5

cos L = 0.8

L = $cos^{-1}(0.8)$

L = 36.9

for meanure of angle N

sin N = 4/5

sin N = 0.8

N = $sin^{-1}(0.8)$

N = 53.1

Answer 2

Answer:

Step-by-step Explanation:

(a) angle L ratio: cosL = 4/5

angle N ratio: sinN = 4/5

(b) m angle L = cos ^-1(4/5) = 37°

m angle N = sin ^-1(4/5) = 53°

(c) m angle L + m angle N = 90°
