Answer: 19.8 Units
Step-by-step explanation:
The triangle is shown in the attached figure, and have three vertices: , and .
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
Answer:
Step-by-step explanation:
Temperature in the room
Decrease in the temperature(outdoors) in .
Rate of decrease
(a) After
But it is not possible as outdoor temperature is so after temperature decrease will not occur.
Hence after more minutes temperature=
(b) Let after temperature is
Here
Answer:
Step-by-step explanation:
We are told that Matt is climbing a mountain. When his elevation is higher than 1600 meters, breathing is difficult for Matt. We are asked to write an inequality that describes h, the elevation at which breathing is difficult for Matt.
We know when elevation (h) will be higher than 1600 meters Matt will face difficulty in breathing. We can represent this situation as: .
Therefore, inequality representing the elevation at which breathing is difficult for Matt will be .
Complementary angles are adjacent angles which add to equal 90 degrees (a right angle). To find m∠A in these figures, set the sum of the known angle measure and the unknown angle measure, A, equal to 90 and solve.
10)
90 = 67 + A
23 = A
m∠A = 23°
11)
90 = 57 + A
33 = A
m∠A = 33°
12)
90 = 44 + A
46 = A
m∠A = 46°
