Her speed will be affected by the speed of the river therefore her speed upstream will be 2.6-0.4 mph and her speed downstream will be 2.6+0.4mph
Therefore upstream it will take 4.4/2.2=2 hours
And downstream it will take 4.4/3=1.47 hours (3sf)
Answer:
a=8
Step-by-step explanation:
-5(a+3)=-55
First you times the bracket by -5
-5a-15=-55
Then you add the 15 to -55 because since the 15 is a negative on the right it has to be the opposite to the left
-5a=-40
Then you divide both sides by negative 5
-5a . = . -40
--------- ----------
- 5 -5
a= 8
he relationship between angle TAM and angle CAS is: vertical angles pair, and they are congruent to each other.
<h3>What are Vertical Angles Pair?</h3>
When two straight lines intersect each other at a point, they form four angles. The pair of angles that are directly opposite each other are referred to as vertical angles pair. These angles are congruent to each other. That is, they have the same angle measures.
The image attached below shows the intersection of two lines, line CT and line SM. They intersect at A to form four angles.
Two pairs of vertically opposite angles were formed. angle TAM and angle CAS is one of the vertical angles pair that was formed.
Therefore, the relationship between angle TAM and angle CAS is: vertical angles pair, and they are congruent to each other.
