Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode
The correct answer is ''b'' because 3/4 is 6/8 and 7/8 is 7/8 so also is 6/7 i hope it helped u
Answer:
2 and 3 are complimentary, and 2 plus 3 is 90 degrees. Therefore 90 minus angle 2 is angle 3.
Answer:3x = -147 : x= -49
Hope I helped!..
Step-by-step explanation:
3x = -147
Divide both sides by 3
3x/3 = -147/3
Simplify:
X = -49
The snowfall in city b would be 7.7 inches I think
