Answer:
136 miles
Step-by-step explanation:
Distance is product of speed and time.
Given the car that moves South takes 2 hours then the speed is 55 mph
D=st
Where s is speed, t is time and D is distance covered. Substituting 2 hours for time and 55 mph for s then
Distance=2*55=110 miles
Using trigonometry
Cos 36°=110/x
X=110/cos 36°=135.967477524977 miles
Alternatively
X=110/sin 54°=135.967477524977
Rounded off, this is approximately 136 miles
Answer:
m∠C = 66°
Step-by-step explanation:
Given
m∠ A = 33°
m∠ B = 81°
To determine
m∠C = ?
We know that sum of angles of a triangle is 180°.
so using the equation
m∠ A + m∠ B + m∠C = 180°
substituting m∠ A = 33°, and m∠ B = 81° in the equatio
33° + 81°+m∠C= 180°
114° + m∠C = 180°
m∠C = 180° - 114°
m∠C = 66°
Therefore,
Answer: It is the 2nd one
Step-by-step explanation: 8≤m
Answer:
47°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180, that is
x = 180° - (48 + 85)° = 180° - 133° = 47°
