Answer:
m∠A = 33.948° or 0.5925 radians
Step-by-step explanation:
cos(A) = (b^2 + c^2 − a^2) / 2bc
cos(A) = (22^2 + 8^2 − 16^2) / 2*22*8 = 0.8295454545 or 73/88
m∠A = arccos(73/88) = 33.94792653
8x+6 <54
subtract 6 from each side
8x < 48
divide by 8
x<6
Choice A
Answer:
B = 22
C = 122
D = 36
Step-by-step explanation:
The angles of a triangle add to 180. Take the measure of each angle add them together. Set them equal to 180.
2x + x + 4 + 7x - 4 = 180
10x = 180
x = 18
To find each angle, substitute x = 18.
Angle B is 18 + 4 = 22
Angle C is 7(18) - 4 = 122
Angle D is 2(18) = 36
