Answer:
The base of the banner is 30 centimeters.
Step-by-step explanation:
Area = base × height
Plug in the numbers:
127 1/2 = b × 4 1/4
Convert mixed fractions into improper fractions for easier calculations.
Improper fraction formula: (denominator × mixed number + numerator)/denoninator
(2 × 127 + 1)/2 = 255/2
(4 × 4 + 1)/4 = 17/4
Rewrite equation:
255/2 = b × 17/4
Isolate variable b by multiplying the reciprocal of 17/4 (which is 4/17).
1020/34 = b
Simplify.
30 = b
6 + 2 < 9 + 3...u r correct
The measure of the fifth angle in the pentagon is 110°.
<h3>
Polygon</h3>
A polygon is a plane figure that has a number of straight line segments connected together to form a closed shape.
Types of polygon are triangle, quadrilateral, pentagon.
A pentagon has 5 sides and the sum of angles in a pentagon is 540°. Hence, let x represent the fifth angle:
x + 90 + 90 + 125 + 125 = 540
x = 110°
The measure of the fifth angle in the pentagon is 110°.

Answer:
If i were you, i'd choose A. but honestly, i could be wrong. But im pretty sure it's A. cause non of the other choices make sense.
Answer:
y = 15
x = 43
Step-by-step explanation:
x + y = 48
x - 2y = 3
3y = 45
y = 15
x + y = 48
x + 15 = 48
x = 43
