Angle C is Equal to 84 as well as angle A.
Answer: Combine like terms!
Step-by-step explanation:
-4x + 3x = 2
-1x = 2
-1x/-1 = 2/-1
x = -2
Answer:
7/2
Step-by-step explanation:
Slope= y2-y1/x2-x1
(12-5)/(-1--3)
-> (7)/(2)
7/2
Answer:
2 or 12
Step-by-step explanation:
The answer that we will use this equation 1/t1 +1/t2=1/ttotal
where t1 is the time of smaller pipe while t2 is the of the larger pipe
Given t total =4 while t2 is equal to t2=t1-6
So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4
8( t1-3)=(t1^2-6t1)
t1^2-14t1+24=0
t1=2 or 12
Let us draw a triangle ABC with A=15° ,B=113° and b=7.
Please see the attached image.
We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have
Apply Sine rule in the triangle ABC, we get
Therefore, we have
