Answer:
What is the question. Please rewrite the question.
Tan x = 8749/675
x= arctan (8749/675) arctan = tan^-1
x=85.59 degrees
<span>1. Measure the distance the solvent front traveled from the baseline (m1). 2. Measure the distance the reactant b spot traveled (the center of the spot) (m2). 3. To determine the rf, divide (m2/m1). 4. Significant figures- use 2 so the answer should be written to the hundredths place as the spot will not travel farther than the solvent front.</span>
Step-by-step explanation:
5) angle 5 = 69°
than, angle 10 = 69° ( alternate interior angle )
6) angle 6 = 115° ( alternate interior angle )
7) angle 7 = 118° ( alternate interior angle )
8) angle 11 = angle 4 - 180
→ 72 - 180 = 108°
therefore, angle 11 = 108°
9) angle 14 = 114° - 180
→ angle 14 = 66°
10) angle 12 = 86° ( alternate interior angle)
hope this answer helps you dear...take care!
