Step-by-step explanation:
Answer:
m=-3
Step-by-step explanation:
For this question you have to solve the equation backwards.
A = 1/2 x (b1 + b2) x h
In order to get rid of the 1/2 (since it's division) multiply each side by 2
now we have: 2A = (b1 + b2) x h
Now do the same to the get rid of the (b1 + b2) (divide each side by it)
2A/(b1 + b2) = h
Answer:
∠ p ≈ 59°
Step-by-step explanation:
Using Pythagoras' identity in right triangle ABD to find DB
DB² = 5² + 6² = 25 + 36 = 61 ( take square root of both sides )
DB =
---------------------------------------
Using the cosine ratio in right triangle DBC
cos p = = = , thus
p = ( ) ≈ 59°
Answer:
x>1 and y>1
Step-by-step explanation:
x+y>2....... (i)
2x-y>1...... (ii)
Adding equations (i) and (ii),
x+y+2x-y>2+1
3x>3
x>3/3
x>1.
Putting the value of x in equation (i),
1+y>2
y>2-1
y>1.
