The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.
Answer:
n = 21 degrees
Step-by-step explanation:
the second triangle is isosceles, so the angles of the base are congruent
a triangle have the sum of the interior angles equals to 180
n + n + 138 = 180
2n = 42
n = 21
You would have to use the Pythagorean theorem to solve this.
Step 1:
-Create a triangle using point (-5,-1)
Step 2:
-Find the base and height of the triangle created.
Base=distance from (-5,0) and point A, (3,-1). (Base is 8 units)
Height=distance from (-5,0) to (-5,5). (Height is 6 units)
Step 3:
Use the Pythagorean Theorem to find the hypotenuse length which is the line segment AC.
8^2+6^2=(AC)^2
64+36=(AC)^2
100=(AC)^2
10=AC
AC is ten units long

please mark me brainliesf if it is right
sin(A)/a = sin(B)/b
Answer:
(a) (i) 8/15
(ii) 4.8 Quips
(b) 5.82 Quips
Step-by-step explanation:
(a)
(i) 1 Gip = 1/15 of a circumference
8 Gips = 8 × 1/15 of a circumference = 8/15 of circumference
(ii) 1 Gips = 1/15 of a circumference
15 Gips = 1 circumference
1 Quips = 1/9 of a circumference
9 Quips = 1 circumference
∴ 15 Gips = 9 Quips
1 Gip = 9/15 Quips
8 Gips = 8 × 9/15 Quips = 4.8 Quips
(b) 9.7 Gips = 9.7 × 9/15 Quips = 5.82 Quips
