Question

Find the measure of 2 angle A + 4 angle B and 5 angle A - 3 angle B if angle = 12° 52' 39" and angle B = 15° 24' 33".​

Answer 1

Answer:

Finding the measure of 2 angle A+4 angle B :

Given that,

angle A= 12 deg 52 prime 39\

angle B=15^ 24 prime 33f

We have to find the value of 2 angle A+4 angle B

Puting the values of angle A and angle B , we get 2*( 12 deg * 52 / 39 \ )+4*(15^ 24/33 prime prime)

2(12 deg + 52l + 39ll) +4*(15^ +24l+33 prime prime)

24 deg + 104l + 78ll + 60 deg + 96l + 132ll

84 deg +200 prime+210 prime prime

84 deg +200 prime+180 prime prime+30 prime prime

84 deg +200 prime+3 prime+30 prime prime

[ 1 prime=60 prime prime]

84 deg + 203l + 30m

84^ +180 prime+ 23l +30 prime prime

84 deg + 3 deg + 23l +30 prime prime

[ 1 deg =60 prime]

87 deg * 23 /30 prime prime

Hence, 87 deg * 23 /30 prime prime is the required answer.
