In ΔABC, the measure of angle A is 5° more than 3 times the measure of angle B. Angle C measures 20°less than angle B. Determine the measures of angles A, B, and C.

A = 122°, B = 39°, C = 19°

Step-by-step explanation:

(5+3B) + B + (B-20) = 180

5B = 195

B = 39°

A = 5 + 3(39) = 122°

C = 39 - 20 = 19°

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
