Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
One of the angles of a triangle measures d°, another measures (3d)°, and the third measures (5d + 54)°. The equation becomes
d + 3d + 5d + 54 = 180
9d + 54 = 180
9d = 180 - 54
9d = 126
d = 126/9
d = 14
First angle is 14 degrees
Second angle is 3 × 14 = 42 degrees
Third angle is 5 × 14 + 54 = 124 degrees
The cosine of an acute angle in a right triangle <span> is the ratio of the length of the adjacent side to the length of the hypotenuse.
</span>If cos(x)=1/2, then:
the adjacent side = 1
the hypotenuse = 2
<span>By the Pythagorean theorem:
</span>the opposite side = √(2² - 1²) = √(4-1) = √3
The sine<span> of an angle is the ratio of the length of the opposite </span>side<span> to the length of the hypotenuse, so:
</span>sin(x) = opposite/hypotenuse = √3/2
The tangent<span> of an angle is the ratio of the length of the opposite side to the length of the adjacent side:
</span>
tan(x) = opposite/adjacent =√3/1 = √3
1) 13 is a prime number.
