Answer:
m= 67.5 and n=56.25
Step-by-step explanation:
180-15=165
165/2= 82.5
90-15= 75
75+75= 150
180-150=30
30+82.5= 112.5
180- 112.5= 67.5
m= 67.5
180-67.5= 112.5
112.5/2= 56.25
n= 56.25
The given triangle is a right-angled triangle. This means that special trig identities can be applies
<u>These identities are as follows:</u>
sin (theta) = opposite / hypotenuse
cos (theta) = adjacent / hypotenuse
tan (theta) = opposite / adjacent
<u>Now, for the unknown theta in the triangle:</u>
The opposite side is 16 and the hypotenuse is 20
This means that we will use the <u>sin</u> not the cos as Bob did
<u>The solution will be as follows:</u>
sin (theta) = opposite / hypotenuse
sin (theta) = 16 / 20
theta = sin^-1(16/20)
theta = 53.13°
Hope this helps :)
