Answer:
x ≈4.244833711
Step-by-step explanation:
x^2=7^2+8^2-2(7)(8)(cos32)
Determine the powers
x^2=49+64-2(7)(8)(cos32)
Multiply from left to right
x^2 = 49+64 - 112cos32
x^2 = 49+64 - 94.98138677
Add and subtract
x^2 =113-94.98138677
x^2 = 18.01861323
Take the square root of each side
sqrt(x^2) = sqrt(18.01861323)
x = sqrt(18.01861323)
x ≈4.244833711
x^2 =113
8(c-12)=40 that gonna be equal to 8c-96=-40 or 8c=-40+96 ,8c =56 divide both sides by 8 that equal to 7.....
Answer:
x = 19
Step-by-step explanation:
(5x + 4)° + (x - 2)° + (3x + 7)° = 180°
(5x + x + 3x)° + (4 - 2 + 7)° = 180°
9x° + 9° = 180° → ÷9
x + 1 = 20
x = 20 - 1
x = 19
