If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
Answer:
a^6*b^6
Step-by-step explanation:
I think that's correct, but I'm not sure
Step-by-step explanation:
Given
x - 2.6 = 1.8
x = 1.8 + 2.6
x = 4.4
Hope it will help :)
3.5 because you turn the negative into the positive and add the 1.5
Circumference of circle is 62.8 inches.
Step-by-step explanation:
Using Formula
Circumference of circle = 2 π r
Substitute the values
Circumference of circle = 2 × 3.14 × 10 inches.
multiply the numbers
Circumference of circle = 62.8 inches
Hence, the circumference of circle is 62.8 inches.
