Answer:
x = 145°
Step-by-step explanation:
We know that y = 98°, so we can find ∠DBC:
180°-y = ∠DBC
180°-98° = 82°
We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.
∠DBC + z = x
82°+63° = x
x = 145°
Answer:
26.15
Step-by-step explanation:
32.2 - 4.7 - 3.75 + 2.4 =26.15
Answer:
opposite sides of a parallelogram are equal
2x+15=x+15
2x-x=15-15
x=0
Answer:
The number of ways = 151200
Step-by-step explanation:
Below is the calculation of the number of ways:
Total number of people = 10
Total number of posts = 6
The number of ways = 10P6
The number of ways = 
The number of ways = 10 x 9 x 8 x 7 x 6 x 5
The number of ways = 151200
