Answer:
The answer is b = 6
Step-by-step explanation:
Area of a triangle= 1/2 × b × h
A = 21, h = 7, b = ?
21 = 1/2 × b × 7 (multiplying through)
21 = 7b/2
Cross multiply
2 × 21 = 7b
42 = 7b
b = 42/7
b = 6
The mean is the average of a given data set and can be obtained by taking the sum of all numbers and dividing that by the amount of numbers in the data set.
58 + 43 + 33 + 69 + 41 + 74 = 318
There are 6 numbers in the data set.
318 / 6 = 53
Answer:
m∠1 = 130°
m∠2 = 158°
Step-by-step explanation:
For the given figure, we have;
The measure of angle m∠1 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;
m∠1 = 99° + 31° = 130°
m∠1 = 130°
Similarly, the measure of angle m∠2 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;
m∠2 = 28° + m∠1 = 28° + 130° = 158°
m∠2 = 158°.
Answer:
see explanation
Step-by-step explanation:
Using 
= i, then i² = ( )² = - 1
and i³ = i² × i = - 1 × i = - i
also
= i² × i² = - 1 × - 1 = 1
We can surmise that i raised to any multiple of 4 will equal 1
Given
( note 35 = 32 + 3 and 32 is a multiple of 4 ), thus
= 
= 1 × i³ = - i
