Answer:
see image; 200; 400
Step-by-step explanation:
y=20x
graph
y is part of a right angle on line AB
a right angle = 90 degrees
90-47 = 43 degrees
y = 43 degrees
a straight line = 180 degrees
180-47 = 133 degrees
x = 133 degrees
Answer:
7, 10, 13
Step-by-step explanation:
1) n = 1: 3(1) + 4 = 3 + 4 = 7
2) n = 2: 3(2) + 4 = 6 + 4 = 10
3) n = 3: 3(3) + 4 = 9 + 4 = 13
11.3 feet.
12 squared (144) minus 4 squared (16) is equal to 128. The square root of 128 is approximately 11.3.
Answer:
C
Step-by-step explanation:
A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.
The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.
Perimeter= 10x +15
Length of each side
= (10x +15) ÷5
= 2x +3
