Step-by-step explanation:
Answer:
8 miles per hour.
Step-by-step explanation:
8 miles per hour you can find this answer by doing 16 divided by 2
Answer:
y=45-3x
Step-by-step explanation:
we want y, which is the number of hours left. to find this, we take:
hours left=total # of hours required - hours worked/day
so:
y=45-3x
(because x could be any number: 2 days, 3 days, etc.)
Answer:
(X + 9)(x -9)
Step-by-step explanation:
Subtraction of perfect squares:
The factors of a subtraction of perfect squares is given by:
What are the factors of x² - 81?
This can be written as:
So
Answer:
Here, Exterior angles are ∠1, ∠2, ∠7 and ∠8
Interior angles are ∠3, ∠4, ∠5 and ∠6
Corresponding angles are ∠
(i) ∠1 and ∠5
(ii) ∠2 and ∠6
(iii) ∠4 and ∠8
(iv) ∠3 and ∠7
Axiom 4 If a transversal intersects two lines such that a pair of corresponding angles is equal, then the two lines are parallel to each other.
Thus, (i) ∠1 = ∠5, (ii) ∠2 = ∠6, (iii) ∠4 = ∠8 and (iv) ∠3 = ∠7
Alternate Interior Angles: (i) ∠4 and ∠6 and (ii) ∠3 and ∠5
Alternate Exterior Angles: (i) ∠1 and ∠7 and (ii) ∠2 and ∠8
If a transversal intersects two parallel lines then each pair of alternate interior and exterior angles are equal.
Alternate Interior Angles: (i) ∠4 = ∠6 and (ii) ∠3 = ∠5
Alternate Exterior Angles: (i) ∠1 = ∠7 and (ii) ∠2 = ∠8
Interior angles on the same side of the transversal line are called the consecutive interior angles or allied angles or co-interior angles. They are as follows: (i) ∠4 and ∠5, and (ii) ∠3 and ∠6
