A = 5a
B = 2x
C = 6x^2
D = 5/7
E = 2/11
F= 6/x^2
G = 6a
H = -7x
Answer:the answer is .B the second one
Step-by-step explanation:
We assume , A, B, and C are angles of a triangle.
The sum of angles of a triangle is equal to 180º; therefore:
A+B+C=180º
B is 45% of angle A; then B=0.45A
C is 35% of anble A; Then C=0.35A
We can suggest this equation;
A+0.45A+0.35A=180
1.8A=180
A=180/1.8
A=100
Answer: The measurement of angle A is 100º.
The exact value for cos(pi/16) would be :
cos (pi/16) = +/- √1+cosa/2
cos (pi/4) = sqrt2/2
