Answer:
- angles: 31.42°, 31.42°, 117.16°
- legs: 23.79 m
Step-by-step explanation:
The base angles can be found from the definition of the tangent function:
tan(base angle) = height/(half-base length)
base angle = arctan(12.4/20.3) ≈ 31.418°
Then the apex angle is double the complement of this:
apex angle = 2(90° -31.418°) ≈ 117.164°
The base angles are 31.42°, and the apex angle is 117.16°.
__
The leg lengths can be computed from the Pythagorean theorem applied to the altitude and the half-base length.
leg length = √(12.4² +20.3²) = √565.85 ≈ 23.789 . . . . meters
The length of the legs is about 23.79 m.
Answer: 10
<u>Step-by-step explanation:</u>
First, find m∠C by using the Triangle Sum Theorem:
∠A + ∠B + ∠C = 180°
110 + 43 + ∠C = 180°
153 + ∠C = 180°
∠C = 27°
Next, Use the Law of Sines to solve for c:
Answer:
The degree of the polynomial is 3
Step-by-step explanation:
Given:
To Find:
The degree of the polynomial= ?
Solution:
The degree of the polynomial is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial
Here in the given polynomial
The terms are
The term has the largest exponent of 3
Note: The degree of the polynomial does not depend on coefficients of the terms
280 is the answer
______________________________________
The mean is the average.
i’ve found this a helpful way to remember:
the medians the middle
the mean old average
