19.941 would round to 20 when rounded to the nearest one.
Answer: x= 108
Step-by-step explanation: The triangle is an isosceles triangle, so the two sides are parallel which means the other angle equals to 72 as well. Now we take the triangle rule and do 180-72-72= 36 (the top angle= 36). The triangles are all equal so that means the other angle (in the upside down one) also equals 72 so we take 36+72= 108. Since it is also a parallelogram, the angles are equal.
Answer:
circumference is 18.84
area is 28.26
Step-by-step explanation:
circumference of a circle is
2πr where r is radius
= 6×3.14= 18.8
area of a circle is πr²
= 3×3×3.14
= 28.26
use π = 3.14
There is many way how to get the length of a triangle. You can use many method but to your question the best method to use is Law of sine and cosine Side Angle Side triangle formula. This formula is this one (a^2 = b^+c^2-2bc*cos(angle)). So if your fill it up it would be (a^2 = 3^2+4^2-2*3*4*cos(60)). The answer would be 3.61
