I'm assuming you're comparing two triangles? If not, then this is probably wrong.
Triangle = 180 degrees
180 divided by 3 = 60 degrees
since ∠1 ≅ ∠2 ≅ ∠3, each angle equal 60 degrees
∠4 ≅ ∠5
m∠4 = m∠3 + 10
m∠3 + 10 = m∠5
we know that m∠3 is 60 degrees.
60 + 10 = 70, so m∠5 is 70 degrees
70 degrees is the answer.
To find the maximum and minimum (5,-9)
Answer:
Option B
Explanation:
According to the given question, we are asked to state the rock layer that must be porous and have enough permeability for fluid to move through the layer.
As a result of this, we can see that we are assuming that fracking has not been used with the oil and gas well and this rock layer would need to be permeable so that fluids can move through it to other areas.
Therefore, the correct answer is option B
The severity of an electric shock depends on following factors:
a) Amperage
i.e. the amount or strength of electric current passing through the body. A larger magnitude of current causes more damage. Large amount of current can cause the organs to burn and ultimately causing death.
b) Duration of the exposure
The duration of exposure to shock is the second factor. If we are exposed to the shock for a longer duration, it will cause more harm as compared to when exposure is short lived.
c) Pathway of electric current in the body
Pathway of electric current matters. If the current passes through the vital body organs and damages them e.g. heart it may lead to death.
Thus the A option from the question is correct answer.
