Assuming that a “circle graph” is a pie chart, the way of solving is this:
The degree of the angle of that pie section is relative to the entire circle just as the number of pyramids are to the number of total building blocks.
The number of pyramids out of the total is 30/150, or 1/5 (20%). This means that the angle of the section will be 1/5 the total angle measurement of the circle.
There are 360 degrees in a circle, and one fifth of this is 72 (360/5). Your answer is C.
Answer:
x = -2
Step-by-step explanation:
T = 2π√(l/g)
<span>=> T = 2π√[5m/(9.8m/s²)] </span>
<span>=> T ≈ 4,49s </span>
Answer:
40°, 80°, 120°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 + 3 = 9 parts
The sum of the interior angles of a quadrilateral is 360°
Divide this by 9 to find the value of one part of the ratio.
360° ÷ 9 = 40° ← value of 1 part of the ratio
Then
2 parts = 2 × 40° = 80°
3 parts = 3 × 40° = 120°
The 4 angles are 40°, 80°, 120°, 120°
