Answer:
Step-by-step explanation:
you can divide both sides by 2.35 to get the right side to be 1:
<u>Given</u>:
Given that ABC is a right triangle.
The length of AB is 7 units.
The measure of ∠A is 65°
We need to determine the length of AC
<u>Length of AC:</u>
The length of AC can be determined using the trigonometric ratio.
Thus, we have;
Where the value of is 65° and the side adjacent to the angle is AC and the side hypotenuse to the angle is AB.
Substituting the values, we have;
Substituting AB = 7, we have;
Multiplying both sides by 7, we get;
Rounding off to the nearest hundredth, we get;
Thus, the length of AC is 2.96 units.
Answer:
6.1 units²
Step-by-step explanation:
area of a triangle= 0.5b*h
b=2
h=6.1
6.1*2=12.2
12.2*0.5= 6.1
Answer:
1.60 L of 10% solution
0.40 L of 35% solution
Step-by-step explanation:
If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:
x + y = 2
0.10x + 0.35y = 0.15(2)
Solve with substitution:
0.10x + 0.35(2 − x) = 0.15(2)
0.10x + 0.70 − 0.35x = 0.30
0.40 = 0.25x
x = 1.60
y = 0.40
Answer: A and B
Explanation: If you draw the graph out it crosses the points (1,2) and (-1,-2) and those are points A and B
