Answer:
D. Obtuse.
Step-by-step explanation:
We are told that in 
and 
. We are asked to classify our given .
We can see that angle M and angle P are acute angles as their measure is less than 90 degrees.
Let us find the measure of angle P using angle sum property of triangles, which states that sum of interior angles of a triangle is 180 degrees.
So we can set an equation as:
Upon substituting our given values we will get,
As measure of angle N is 98 degrees, so angle N is an obtuse angle.
Since a triangle having an angle that measures more than 90 degrees is called an obtuse triangle, therefore, is an obtuse triangle and option D is the correct choice.
Answer:
Step-by-step explanation: letter B is the right answer
Answer:
5 percent per annum
Step-by-step explanation:
interest rate:
interest: $1800
principal: $18000
duration: 2 years
1800/ 18000 * 100
result is 10%
Since interest is 10% in 2 years, 10% / 2
interest is 5% per year.
Answer:
Slope = 2
Step-by-step explanation:
Slope = 20/10 = 2
Correct answer is: distance from D to AB is 6cm
Solution:-
Let us assume E is the altitude drawn from D to AB.
Given that m∠ACB=120° and ABC is isosceles which means
m∠ABC=m∠BAC = 
And AC= BC
Let AC=BC=x
Then from ΔACD , cos(∠ACD) = 
Since DCB is a straight line m∠ACD+m∠ACB =180
m∠ACD = 180-m∠ACB = 60
Hence 
Now let us consider ΔBDE, sin(∠DBE) =
