Answer:
17.2°
Explanations
To find angle A, use the cosine rule.
a^2 = b^2 + c^2 - 2 × a × c cos A
4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A
16 = 49+ 100 - 140 × cosA
16 = 149 - 140cosA
16- 149 = - 140cosA
-133 = - 140cosA
cosA = 133/140
cosA = 0.95
A = 17.2°
Answer:
the distance is 15
Step-by-step explanation:
because if we take away the negative on the -10 and make it positive 10 and add 5 it would be 15 spaces
No, they are not equivalent.
5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.
(using distribution property)
