Answer:
h = 19cm
Step-by-step explanation:
The area of a parallelogram =
A = bh
285cm² = 19×h
285 = 19h
divide by 19
285/19 = 19h/19
h = 15cm
Answer:
15) For a regular polygon of N sides, the measure of one interior angle is:
A = (N - 2)*180°/N
In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:
A = (11 - 2)*180°/11
A = 9*180°/11 = 147.27°
Rounding to the first decimal after the decimal point, we get:
A = 147.3°
Then the correct option is B.
16) We know that the length of all the sides of a square is the same.
In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4
And those lengths must be the same, then we have the equation:
2x + 4 = 4
subtracting 4 in each side of the equation we get:
2x + 4 - 4 = 4 - 4
2x = 0
The only solution for this equation is x = 0.
Then the correct option is C
Answer:
Step-by-step explanation:
The angle formed by two secants is half the difference of intercepted arcs.
- 46 = 1/2(x - 57)
- x - 57 = 46*2
- x = 57 + 92
- x = 149
Correct choice is B
There correct answer to that question is 22.45
82, because the rest are perfect squares
