The dirty little secret about trig is students mostly just need to understand the 45/45/90 right isosceles triangle and the 30/60/90 triangle, which is half an isosceles triangle.
I'm sure you have seen it many times already, so I'll remind you in the 30/60/90 right triangle the sides opposite those angles are respectively in the ratio
. Remember the smallest side is always opposite the smallest angle, etc. These make a right triangle because
So in this hypotenuse 2 triangle, the length 1 side is opposite the 30 degree angle and the
side is adjacent to it.
We could jump right to the answer but let's enumerate all the trig functions. Really you should memorize the sine and cosine so you can get these quickly.
We want the cotangent, another way to get it is
.21 times 611=128.31
128.31 plus 611
739.31
Answer:
A. 52°
Step-by-step explanation:
The measure of an inscribed angle is 1/2 the measure of the intercepted arc.
m∠B = 1/2 (m of arc AC)
26 = 1/2 (m of arc AC)
52 = (m of arc AC)
<u>ANSWER: </u>
The algebraic expression for one-eight of the sum of a number and three is 
<u>SOLUTION:
</u>
Given, "x" represent the unknown value.
We have to write the algebraic expression for:Here, the number is unknown term, so x represents the number.
Now according to given information ,
One - eight of the sum of a number and three.
→ 
of the sum of x and 3
→ 
→ 
→
Hence the algebraic expression for one-eight of the sum of a number and three is
Answer:
58100
Step-by-step explanation:
The way I see it is move the decimal point over to the right (or left depending on whether its negative or not) however many units the exponent says. After it moves over the number, add the zeroes for the remaining amount of spaces until you have moved it over the correct amount. I'm not sure if that made any sense, but I know the answer is correct.
