Answer:
C
Step-by-step explanation:
∠ AFD = ∠ AFC + ∠ CFD
Given ∠ CFA = 90° and
∠ CFD = 90° - ∠ EFD, that is
∠ CFD = 90° - 62° = 28°, thus
∠ AFD = 90° + 28° = 118° → C
Answer:
x = 2.4
Step-by-step explanation:
For this equation, you need to use trigonometry. we only need to use one of the two angles given and for this example i'm going to use the 60° angle. as we know the adjacent side and want to know the opposite side, we need to use the trig ratio tan
in this case, we will replace the adjacent side with
the square root of 2.
= 
as the side we know is on the bottom of the ratio, we need to multiply it by the ratio (tan) then the angle (in case you don't know, * means multiply)
round to 1 decimal place
x = 2.4
Hope this was helpful :-)
I'm sorry if this was confusing, trigonometry is very hard to explain.
Let’s first cut/separate this figure into two shapes: rectangle and a triangle
The area of the rectangle: 9 • 2 = 18
The area of the triangle: 1/2 • 8 • 4 = 16
The total area: 18 + 16 = 34

Answer:
BC, DB, CD
Step-by-step explanation:
The side opposite the largest angle must be the largest side and the side opposite the smallest angle must be the shortest. 96 degrees is opposite CD and 30 degrees is opposite BC.
