Answer:
in radian <em>measure</em>
<em>theta=</em><em>length </em><em>of </em><em>arc </em><em>/</em><em>radius </em>
<em>so </em><em>a</em><em>=</em><em>l/</em><em>r</em>
<em>a</em><em>=</em><em>5</em><em>6</em><em>/</em><em>7</em><em>0</em>
<em>a</em><em>=</em><em>4</em><em>/</em><em>5</em>
Step-by-step explanation:
a= theta angle in radian
A line is 180° so if you are given 43°on part of line l
180-43=137
So x=137°
Answer:
x ≈ 80.4
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan15° = 
= 
( multiply both sides by 300 )
300 × tan15° = x , then
x ≈ 80.4 ( to the nearest tenth )
Answer: I think it is 4 places to the left.
Step-by-step explanation: Usually when dividing numbers like 1000, 100, etc. with decimals, I count the amount of zeros and then move the decimal point to the left the amount of zeros there are. When you multiply you move the decimal to the right, when you divide you move the decimal to the left.
