Answer:
30/4
Step-by-step explanation:
7 times 4 = 28
28+2=30
Hi there!
In order to solve for x, we'll need to use a trigonometry ratio. In this case, we'll use tangent, which is opposite over adjacent.
Here is our equation:
tan(37)/1 = x/2.1
Cross-Multiply:
x = tan(37) * 2.1
Solve:
x = 1.8 (rounded to the nearest tenth)
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

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
