1. Given the information below, solve the triangle. If the information results in more than one triangle,

solve each triangle that results.

a = 86, B = 58°; A = 84° ; find b, C, and c

2.Given the information below, solve the triangle. If the information results in more than one triangle,

solve each triangle that results.

c = 25, b=24 ; find a, A, and B

• 1. a = 86, A = 84 deg, B = 58 deg. Find b, C and C.;

By law of sines, a/sinA = b/sinB = c/sinC;

b = (sinB/sinA)a = (sin58/sin84)(86) = (0.8480480962/0.9945218954)(86) =;

73.33386687.;

C = 180 - (A+B) = 180 - (84+58) = 180-142 = 38 deg;

c = (sinC/sinA)a = (0.6156614753/0.9945218954)(86) = 0.6190527108(86);

= 53.23853313.;

2. c = 25, b = 24. Find a, A and B.;

c^2 - b^2 = 25^2 - 24^2 = (25-24)(25+24) = 49 = 7^2 = a^2. Then a = 7.;

A = arctan(7/24) = arctan(0.2916666667) = 16.26020471 deg.;

c, the hypotenuse, is opposite right angle C = 90 deg;

Then B = (90-A) deg = (90-16.26020471) deg = 73.73979529 deg.;

Not a question. 2 points for me, thanks!

• 1.

Given the information below, solve the triangle.

If the information results in more than one triangle,

solve each triangle that results.

a = 86, B = 58°; A = 84° ; find b, C, and c

b: 73.33

c: 53.24

C: 38.00°

2.

Given the information below, solve the triangle.

If the information results in more than one triangle,

solve each triangle that results.

c = 25, b = 24 ; find a, A, and B

Enter three values and calculate.
