Answer:
4
Step-by-step explanation:
the third angle of the inner triangle is defined by using the rule that the sum of all angles in a triangle must be 180 degrees. let's call this angle a
180 = 48 + 16x + a
132 - 16x = a
and then we know that both angles, 28x and a together must also be 180, as they are complementing each other to cover the whole top of the base line.
so,
28x + 132 - 16x = 180
12x = 48
x = 4
Answer:
1/52
Step-by-step explanation:
A deck has 52 cards and the probability of picking a specific one is 1/52, or 1.92%
If you are looking for the probability of a diamond, it is 1/4, or 25%
Answer:
18.7 mph
Step-by-step explanation:
768.57m / 41.1h = 18.7 mph
Answer:
50
Step-by-step explanation:
since all angles add up to 180
and since this is a right triangle the square in the corner is 90 degrees
so 40+90+x=180
130+x=180
subtract 130 from both sides
130-130+x=180-130
x=50
Hope that helps :)
