Since the sum of three angles in a triangle is equal to 180 degrees, you may find the measurement of the third angle by subtracting the sum of the other two angles from 180 degrees. Hence, 180-78 (in degrees) would result in your desired answer.
Answer:
19.44x and 12.96x+19.44
Step-by-step explanation:
Given data
Circle 1 radius =3x.
Circle 2 radius = 2x+3
The expression for the circumference is
C= 2πr
Circle 1 radius =3x.
C= 2*3.24*(3x)
C= 19.44x
Circle 1 radius = 2x+3
C= 2*3.24*(2x+3)
C=6.48*(2x+3)
C=12.96x+19.44
The measure of each of the angles formed is 32 degrees.
150 leaves -----100 %
177 leaves ----- x %
------------------------------
150 : 177 = 100 : x
x = ( 177 * 100 ) : 150
x = 118 %
118 5 - 100 % = 18%
Answer: Her collection increased by D ) 18 %
Answer:
1. x = 2, y = -2 prod: -4 / 2 = -2
2. x = 6, y = -6 prod: -36 / 2 = -13
3. x = -1, y = -1 prod: 1 / 2 = 0.5
4. x = -4, y = -1 prod: 4 / 2 = 2
5. x = 10, y = -1 prod: -10 / 2 = -5
