Solve the triangle.

Mathematics
1 answer:
Brrunno [24]4 years ago
5 0

Answer:

a ≈ 11.3, C ≈ 24.2, B ≈ 103.8

Step-by-step explanation:

The information A = 52°, b = 14, c = 6 lends itself to solution using the Law of Cosines:  a^2 = b^2 + c^2 - 2bc cos A.

Here, a^2 = 14^2 + 6^2 - 2(14)(6) cos 52 degrees, or

                 = 196 + 36 - 168 (0.616)

                  = 120.57

Taking the positive square root of this results in a = 11.3.

This corresponds to the second answer choice:  a ≈ 11.3, C ≈ 24.2, B ≈ 103.8

Y=2x+6 We know the y intercept is +6 so we still can’t eliminate any of the options. We know it can’t be 1/3x or 1/2x because the y value is greater than the x value. (6)(2)+6=18

Simplify inside the parentheses by dividing coefficients, subtracting the exponents on like bases, and raising the resulting expression to the –3 power. Then, write bases with positive exponents.

Raise the numerator and denominator to the –3 power. Then, using the power of a power property, multiply the exponents. Divide the coefficients and subtract the exponents on like bases, then write with positive exponents.
