Answer: 137... well i think because 180-43= to 137.
I got shot in the Hebrew morning I was going on the same day lol I was going on the balls in
Answer:
steps below
Step-by-step explanation:
3.2.1 AD = DB* sin 2 = DB * sin θ .. DE // AB ∠2= θ ... (1)
By laws of sines: DB / sin ∠5 = x / sin ∠4
∠4 = θ-α ∠5 = 180°-<u>∠1</u>-∠4 = 180°-<u>∠3</u>-∠4 = 180°-(90°-θ)-(θ-α)) = 90°+α
DB = (x*sin ∠5)/sin (θ-α)
= (x* sin (90°+α)) / sin (θ-α)
AD = DB*sinθ
= (x* sin (90°+α))*sinθ / sin (θ-α)
= x* (sin90°cosα+cos90°sinα)*sinθ / sin (θ-α) .... sin90°=1, cos90°=0
= x* cosα* sinθ / sin (θ-α)
3.2.2 Please apply Laws of sines to calculate the length
Answer:
Option (4)
Step-by-step explanation:
From the figure attached,
∠b = 75° [Vertical angles]
If the lines f and g are parallel then,
∠b = ∠c [Corresponding angles]
Therefore, ∠c = 75°
Since m∠c + m∠d = 180° [Supplementary angles]
75° + m∠d = 180°
m∠d = 180° - 75°
m∠d = 105°
Therefore, measure of angle d should be equal to 105° to prove f and g are parallel.
Option (4) will be the answer.
Answer:
c) XY > RS
= true
Step-by-step explanation:
Firstly know the meaning of each sign given
> means <u>is greater than</u>
= means <u>is equal to</u>
a)XZ > ST
XZ = 8
ST = 11 - greater
= false
b) XY = RS
Due to the angles presented, we conclude that the greater the angle, the longer the unmeasured line.
XY is longer than RS
= false
c) XY > RS
= true
d) RS > XY
RS is shorter than XY hence not greater.
= false
