Answer:
∠B
Step-by-step explanation:
To convert from radians to degrees, multiply the radians by 180°/π
⇒ ∠B = 4 × 180°/π
⇒ ∠B = 229.2° (nearest tenth)
As 229.2° > 210° then ∠B is bigger than ∠A
Answer:
m∠A + m∠B = 155
Step-by-step explanation:
ABC is an isosceles triangle that has a 130° angle at vertex B
then
m∠A = (180 - 130)/2 = 50/2 = 25 = m∠C
then
m∠A = m∠C = 25°
