Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
Answer:
The = sign
Step-by-step explanation:
1 11/20 = 31/20 = 1.55 and 1.55 =1.55
I would say 36.8
But I am it sure
2 and 3 are prime numbers, so it means that the greatest common factor is:
G.C.M(2;3)=2*3=6
Product means multiply so 2,681 times 4 = 10,724
