Answer:
The base of the triangle should be 2 feet
Step-by-step explanation:
Let the base of the triangle be y
She wants the height of the banner to be 4 times as tall as the width of the base of the triangle
So height is = = 4y
Now we know that the area of the triangle is =
we also know that total area of the banner is 8 feet squared
Then
y = 2
Width if the base of the triangle is 2 feet
We are given with the following value:
AB = BC =90 cm
∠B =25°
∠D=90°
Solving the ∠C:
180 ° = (∠B/2) + ∠D +∠C
180° = (25°/2) + 90° + ∠C
180° - 12.5° -90° = ∠C
∠C = 77.5°
Solving for length in mD:
sin 77.5° = mD/90
mD = 90 sin77.5°
mD = 87.87
Solving for mDC:
cos 77.5 = mDC/90
mDC = 90 cos 77.5°
mDC = 19.48
Area = 1/2 * Base * Height
Area = 1/2 * 19.48*87.87
Area = 855.834
The total area of triangular pennant = 2 x 855.834 = 1,711.67 cm².
The area is 1,711.67 cm².
Answer:
C) 99 + 3x
Step-by-step explanation:
Since it's always going to cost 99, it'll stay like that since it's a constant
Since it's 3 PER person, that means 3 will have a variable: 3x
