Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
Answer: -8+10s-24t+4u
Steps: Multiply the parantheses by -2
-2×4-2×(-5s)-2×12t-2×(-2u)
Multiply the numbers and calculate the product.
-8+10s-2×12t-2×(-2u) → -8+10s-24t-2×(-2u) → -8+10s-24t+2×2u
And you get -8+10s-24t+4u
