Step-by-step explanation:
(cos 10° − sin 10°) / (cos 10° + sin 10°)
Rewrite 10° as 45° − 35°.
(cos(45° − 35°) − sin(45° − 35°)) / (cos(45° − 35°) + sin(45° − 35°))
Use angle difference formulas.
(cos 45° cos 35° + sin 45° sin 35° − sin 45° cos 35° + cos 45° sin 35°) / (cos 45° cos 35° + sin 45° sin 35° + sin 45° cos 35° − cos 45° sin 35°)
sin 45° = cos 45°, so dividing:
(cos 35° + sin 35° − cos 35° + sin 35°) / (cos 35° + sin 35° + cos 35° − sin 35°)
Combining like terms:
(2 sin 35°) / (2 cos 35°)
Dividing:
tan 35°
The sum of their age is "s" years? Please fix the typo. Then I might be able to help :D
Step-by-step explanation:
I think the answer is 3x square multiplied by 1
Coz anything raised to power 0 will always equal to 1
Answer:
4
Step-by-step explanation:
Use PEDMAS
18 - 6(2+4-1+2) ÷ 3
18 - 6(6 - 1 + 2) ÷ 3
18 - 6(5 + 2) ÷ 3
18 - 6(7) ÷ 3
18 - 42 ÷ 3
18 - 14
4
Hope this helps!
