Check the picture below, the height there uses feet, but nevermind that, we can simply let it be meters, like in this case.
how hight does it go? well, that'd be the y-coordinate of the vertex.
how long does it take? well, that'd be the x-coordinate of the vertex.
1. answer
There is 16 rows in auditorium hall.
Answer:
The measure of angle ADE is equal to 62 degrees.
Step-by-step explanation:
Firstly, I want to remind you that the sum of the interior angles in a quadrilateral are 360 degrees. Now, we are given that CD || BA and CB || DA, which means that this quadrilateral is a parallelogram. This is important because we know that the opposite angles in a parallelogram are congruent, which means that angle C is congruent to angle A and angle B is congruent to angle D. Therefore, the measure of angle A is also 73 degrees. Next, we can represent angle D as x, which means that angle B is equal to x, so the sum of angle D and B is 2x. Finally, we can set up an equation where we solve for the value of x, and then subtract it with 45 degrees:
2x + 2(73) = 360
2x + 146 = 360
2x = 214
x = 107 = B = D
Now, we can subtract the measure of angle D with 45 degrees to get the measure of angle ADE:
ADE = 107 - 45
ADE = 62
I'm on a phone right now so I may mess up.
In this question you have to take advantage of corresponding parts. You can find the angle beside the 65 degree angle by doing 180-65=115. Using your understanding of corresponding parts you can now conclude that 55+x=115. Now you just do the algebra and you get x=60
Answer:
50²
Step-by-step explanation:
(2×10⁵) ÷ (4×10²)
2 × 100000 ÷ 4 × 100
200000 ÷ 400
= 500
= 50²
