Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.
sin(I) = 
To solve, you can use your calculator and the inverse sine function (sin^-1).
I = sin^-1()
I = 61 degrees
Hope this helps!
The side labeled "a" is made the longer side. These are the two congruent sides. So a > b.
We are told that the longer side is 6.3, so a = 6.3, meaning that
2a+b = 15.7
2(6.3)+b = 15.7
12.6+b = 15.7
b = 15.7-12.6
b = 3.1
The triangle has sides of: 6.3, 6.3, 3.1
The perimeter is 6.3+6.3+3.1 = 15.7
Going back to the question "which equation can be used to find the length of the base?", it sounds like either you were given a list of multiple choice answers, or you just fill in the blank. If multiple choice, then try to see which answer matches with what I wrote above. If fill in the blank, then I would just enter either 2(6.3)+b = 15.7 or 12.6+b = 15.7
Answer: 31°
Step-by-step explanation:
180° - 149° = 31°
Answer:
Step-by-step explanation:
<u>According to the graph, the line has the following intercepts.</u>
- y - intercept of (0, - 3)
- x - intercept of (6, 0)
<u>The line equation is:</u>
<u>The slope is:</u>
- m = (0 - (-3)) / (6 - 0) = 3/6 = 1/2
<u>The line is:</u>
Answer:
$104
Step-by-step explanation:
So, in one hour it would cost $13. Times 8, because we want to see what would be the cost for 8 hours, and 8 times 13 is 104.
