Answer:
The value of angle C is 34°
Explanation:
2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}
or, 6x + 6° = 180°
or, 6x = 180° - 6°
or, x = 174°/6
or, x = 29°
now,
value of angle C = x+5°
= 29°+5°
= 34°
I remember doing the last question.
If you recall, x = 29
Just plug 29 into x for each angle
A = 3(29) = 87
B = 2(29) + 1 = 59
C = 29 + 5 = 34
