Answer:
A. √13
Step-by-step explanation:
You can make an educated guess and come to the right conclusion.
The triangle is nearly an equilateral triangle. A triangle with two sides 3 and an angle of 60° would have a third side of 3. A triangle with two sides of 4 and an angle of 60° would have a third side of 4.
So, the third side must be between 3 and 4. Here is an evaluation of the answer choices:
__
A -- between 3 and 4, the correct choice
B -- 3, too short
C -- 1.73, too short
D -- more than 4, too long
__
The question can be answered using your triangle solver app on your calculator, or using the Law of Cosines.
c = √(a^2 +b^2 -2ab·cos(C))
c = √(3^2 +4^2 -2·3·4·(1/2)) = √(9 +16 -12)
c = √13 . . . . . length of the side opposite the 60° angle
Answer:
Step-by-step explanation:
divide by 0.15, and this is x+3000
He was there for 3 hours cause 3 x 35 = 105 but 105 + 55 = 160
Answer:
x = 8
Step-by-step explanation:
since it's a collinerar
or, AB+BC=AC
or, 3x+5x+10 = 74
or, 8x = 74-10
or, 8x = 64
or, x = 64/8
x = 8
<em>Note:</em>
<em>Your questions sound a little unclear.</em>
<em>But, I am assuming your questions as:</em>
<em>''70% of x is 14 min. Find the value of x''.</em>
<em>So, I will solve assuming this statement which anyways would clear your concept. </em>
Answer:
The value of x = 20.
Step-by-step explanation:
Given
<em>''70% of x is 14 min. Find the value of x''.</em>
Thus,
70% of x = 14
70/100 × x = 14
0.7x = 14
divide both sides by 0.7
0.7x/0.7 = 14/0.7
x = 20
Therefore, we conclude that the value of x = 20.
