105°
Step-by-step explanation:
< 3 = 50° + 55° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
<3 = 105°
Answer:
look below
Step-by-step explanation:
thing to note:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite= side across angle you are using
hypotenuse= side across 90 degree angle
adjacent= remaining side
angle B
sin = 6/10
cos = 8/10
tan = 6/8
angle C
sin = 8/10
cos = 6/10
tan = 8/6
hope that helped. let me know if you have any questions:)
2.5*7 = 17.5. If it's easier for you, multiply 2.5 by 5 then add 2.5*2.
