Step-by-step explanation:
Hello There!
The following angles are complementary angles
Complementary angles have a sum of 90
So to solve for the variable (x) we use this equation
90 = 35 + 4x + 7
step 1 combine like terms
35+7=42
now we have
90 = 4x + 42
step 2 subtract 42 from each side
90 - 42 = 48
42 - 42 cancels out
now we have
48 = 4x
step 3 divide each side by 4
4x/4 = x
48 / 4 = 12
we're left with x=12

Answer: 19.1</h3>
====================================================
Work Shown:
tan(angle) = opposite/adjacent
tan(C) = AB/BC
tan(theta) = x/BC
tan(23) = (8.1)/BC
BC*tan(23) = 8.1
BC = (8.1)/tan(23)
BC = 19.0824041631723
BC = 19.1
In this case, rounding to 3 sig figs means we round to the nearest tenth.
Make sure your calculator is in degree mode.
