Answer:
- 508
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus
= - 28 + (- 6 × 80) = - 28 - 480 = - 508
Yes, all of the rhombuses have 2 pairs of parallel side.
Given:
The number is
.
To find:
The location of the given number of the number line.
Solution:
We have,

It can be written as



It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.
The mixed fraction form of given number is



Divide the number in 5 equal parts between two consecutive integers.
Now each unit represents
.
Since
, therefore, it is 2 units left from -1.
The number line is given below.
Answer:
m∠A and m∠B = 130°
m∠D = 50°
Step-by-step explanation:
If all angles equal 360° and angles A and B are equal then we know the A + D and B + C equal 180° then it's simple subtraction to figure out the degrees of all the angles
