Answer:
AB = 5.6 cm
Step-by-step explanation:
To find the length of side AB, which is one of the sides of right angled triangle ABC given above, we would apply the trigonometric ratio formula.
The given angle (θ) = 62°
Length of hypotenuse = BC = 12 cm
Length of adjacent side = AB = ?
We would use the following trigonometric ratio formula:
Cos(θ) = adjacent/hypotenuse
Multiply both sides by 12 to make AB the subject of formula
Length of side AB = 5.6 cm (approximated to 1 decimal place)
Answer:
D.
F.
Step-by-step explanation:
We have been given an image of a triangle and we are asked to choose the remote interior angles of angle 1.
Since we know that remote interior angles are the two angles that are inside the triangle and opposite from the exterior angle.
We can see that angle 1 is exterior angle of our triangle and and angle 4 an 6 are opposite interior angles of angle 1.
Therefore, angle 4 and angle 6 will be remote interior angles of angle 1 and options D and F are correct choices.
