Answer:
The measure of the sides is 20 cm.
Step-by-step explanation:
Opposite side of a parallelogram:
Opposite sides of a parallelogram are congruent, that is, they have the same measure.
Measures (2x+10) cm and (x+15) cm:
This means that:
2x + 10 = 2*5 + 10 = 10 + 10 = 20
The measure of the sides is 20 cm.
All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
Answer:
M equals 9.3
Step-by-step explanation:
To get m alone add 4.2 to each side
<h2>
Answer: 55 degrees</h2>
Step-by-step explanation:
Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles 
, 
and 
:
Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:
Finally:
Answer:
1/30
Step-by-step explanation:
let, vanilla be the first ice cream.
hence, the probability of choosing vanila= 1/6
let, chocolate be the second ice cream.
hence, the probability of choosing chocolate=1/5
hence, the probability that the next customer's sundae will have vanilla and chocolate (in either order)= (1/6)×(1/5)
=1/30
