Answer:
No solution is possible from the given information
Step-by-step explanation:
Triangle ABC is NOT shown below
Without the triangle it's not possible to answer.
Answer:
I believe it is distributive because you are finding the products. Yes, the numbers are mixed up but the parenthesis often involve distributive property.
The answer would be 119 and 4/7
Answer:
2√3
Step-by-step explanation:
You recognize this as a 30°-60°-90° triangle, so you know the hypotenuse (R) is twice the length of the shortest side (√3).
The magnitude of R is 2√3.
_____
In case you haven't memorized the ratios for a 30°-60°-90° triangle, you can use trigonometry and the fact that ...
Sin = Opposite/Hypotenuse
sin(30°) = √3/R
R = √3/sin(30°) = √3/(1/2) = 2√3
Of course, doing this on your calculator will give a numerical answer, which you may not want.
17) let the unknown be x.
tanx = 3.5
x = tan⁻¹(3.5) use your calculator
x ≈ 74.05° x ≈ 74.1 to the nearest tenth
18)
tan 34 = x/20
20*tan34 = x
20*(0.6745) ≈ x
13.49 ≈x
x ≈ 13.49 x ≈ 13.5 to the nearest tenth
19) tan2° = 2/x
x = 2/tan2°
x = 2/0.0349
x ≈57.31 x ≈ 57.31 to the nearest tenth
20) tanx = 90
x = tan⁻¹(90) Use your calculator
x ≈ 89.36°
x ≈ 89.4° to the nearest tenth.
