Important:
The sum of the three angles inside
every triangle is always 180°.
First, look at the left triangle alone.
Two of its angles are 46° and 58° . (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'.
x = 76° .
At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But x = 76°.
So z = (180° - 76°). z = 104° .
Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and z = 104°.
(13° + 104°) = 117° .
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
y = 63° .
Answer: for total order (T*7)+12= $40
for a single person = 1*7+12= $19
Step-by-step explanation:
T= number of tickets
also equals depending on scenario
T= 4 number of friends and himself
Answer:
Step-by-step explanation:
The given equality is
Take the term to the left hand side. This means the term will be divided by
Now since both the numerator and denominator have negative sign the value of fraction will be positive.
Now and
So, the missing factor
0.75 (decimal) is equal to 3/4 (simplified fraction)
