Answer:
(√2)/2; (√2)/2; 1; √2
Step-by-step explanation:
sin A = cos A
1. sin A
sin A/cos A = tan A = 1
A = arctan 1 = 45°
sin A = sin(45°) = (√2)/2
2. cos A
cos A = sin A = (√2)/2
3. cot A
tan A = 1
cot A = 1/tan A = 1/1 = 1
4. sec A
sec A = 1/cos A = 1 ÷ (√2/2) =1 × 2/√2 = √2
Answer:
1. 32 * (-12) = negative
2. 4.75 * (-2.4) < 3 = negative
3. (-2.15) * (-14.6) = positive
4. (-2) (-3) × (-7) = negative
5. 10.5*(-2)*(-3.5) = positive
6. (-3.7)*(-2.6)*(-0.7)x4 = negative
