So, We Know That The Figure Shown Is A Square. So, We Need To Find The Area:
70*70 = 4900.
So, We Have:
490 - (Area Of The Triangle) = A
So, Lets Find The Area Of The Triangle.
(35*70)/2
Well, 35*70 = 2450.
So:
2450/2 = 1225.
Now, Do:
4900 - 1225 = A
4900 - 1225 = 3675
So:
3675cm² = A
Question 1:Look at the first attached image.
We want to solve for the height of the smaller building. Let's start by making a right triangle with angle of 15 degrees and adjacent side of 51 m.
Let's solve for the other leg. Multiply the tangent with 51 m to get the length of the other leg.


Now, subtract that from 207 to get the height of the smaller building.

That's your answer.
Question 2:
The angle of elevation is congruent to the angle of depression because they are alternate interior angles.
Thus, you can choose the 1st and 4th choices as your answer.
Question 3:Look at the second attached image.
Angle E is congruent to angle D for the same reasons mentioned in the last question.
We can create an equation.

Distributive property

Subtract both sides by 1 and 2x

Since E and D are congruent, just plug this value into one of the equations for E or D. You get 46.
The third choice is your answer. Hope this helps! :)
Answer:
The y-intercept is (0, 4).
Step-by-step explanation:
At the y-intercept x = 0 so
y = 4(3^0)
y = 4*1 = 4.
So the y-intercept is (0, 4).
Counting numbers is like the numbers 1,2,3,4,5 and so on they were numbers you were probably taught to count to like to count through 1-10 or whatever. Counting numbers mean to count since they do have the word counting in them.
Whole number just means a number with no fraction or intger also 1 - infinity
