Answer:
0.45=9/20
27/50=0.54
4/5=80
17/25=0.68
38%=19/50
Step-by-step explanation:
1st angle - x⁰
2nd angle - (x+25)⁰
The angles are supplementary,
so
x+x+25=180
2x=155
x=77.5⁰ -1st angle
77.5+25=102.5⁰ - 2nd angle
Answer:
Explanation:
AB = BC
=> Triangle ABC is an Isosceles Triangle
Thus, Angle C = Angle A
DE = BE
=> Triangle DEB is an Isosceles Triangle
Thus, Angle D = Angle B
Proof that triangle ABC and DEB are similar:
Angle DBE = Angle A (corresponding angle)
Angle BDE = Angle C (Both Triangle are Isosceles, if one pair of the angle are equal then the other pair should also be equal)
=> Triangle ABC ~ Triangle DEB (AA)
Therefore, Angle E = Angle B
Find angle B:
Angle C + Angle A + Angle B = 180
40 + 40 + angle B = 180
Angle B = 180 - 80
Angle B = 100 degree
But Angle B = Angle E = 100 degree
Therefore, Angle E = 100 degree
Answer:
The answer is $26
Step-by-step explanation:
The pet store sold 2 kittens for $9 each which makes that 9+9 which equals 18
Now they sold 1 puppy for $8 so to get the total all together you will add 18+8 which equals 26. Thus they earned $26
