Answer:
I think it's -180
Step-by-step explanation:
He keeps descending -15 feet every 1 minute
1 x -15 = -15
2 x -15 = -30
12 x -15 = -180
A triangle's angles will always equal up to 180. Since you already have to of the angles, you will add them up together. 30+20=50. Then, you take 180 and subtract it by the sum of the two previous angles. 180-50=130. Now you know the last angle is 130. You also know that the missing angle is also 130. The reason for that is because the two angles are the exact same if you look at it.
64x2.40 = 153.6
64x1.90 = 121.6
add 153.6 to 121.6
275.2
Answer:
The length of line segment GF is 6.49 units.
Step-by-step explanation:
Given:
In Right angle Triangle Δ EFG,
∠ G = 90°
EF = 9.4 = Hypotenuse (say)
EG = 6.8 = Longer Leg (say)
To Find:
GF = Shorter Leg (say)?
Solution:
In Right angle Triangle Δ EFG By Pythagoras theorem we have,
Substituting the given values we get
The length of line segment GF is 6.49 units.
