Answer:
C. 73 if I have read the given angle measurements correctly.
The angle measurements I see are:


.
Step-by-step explanation:
Those angles together form a full rotation. A full rotation is equal to 360 degrees.
So we have the following equation to solve:

Combine like terms:

Simplify:


Divide both sides be 2:

Subtract 107 on both sides:


Answer:
Given :
→x-y=12
→xy= 3²
=9
Equation formed:

Step by step explanation:

hope it helped you:)
Soooooo sorry but I only understood part a and c.
sorry

<span>We can
use the Pythagorean Theorem (A² + B² = C²) to solve for the lengths of the
sides. We know that the diagonal, C, is 30 meters long, so C² = 900 meters.
We know that since the park is square, A² + B² = 2A² = 2B²
900 = 2A²
A^2 = 450
Taking the square root of 450, we find that the lengths of A and B are
roughly 21.2 meters.</span>

Answer:
10.59%
Step-by-step explanation:
percentage of change is given by
{(old number - new number)/old number} * 100
_________________________
given
no. of student went to the first school dance = 340
no. of student went to the last school dance = 306
Percentage of change between two dance
= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100
= (340 - 306)/340 *100
= (36/340 )*100 = 10.59%
The percent of change between the two dances 10.59%.
