Now you have the answer to four questions!
Answer:
1.90.93
2.90.27
Step-by-step explanation:
1 Simplify a-3a+5a−3a+5 to -2a+5−2a+5
-2a+5-(-a+2b+3)−2a+5−(−a+2b+3)
2 Simplify brackets
-2a+5+a-2b-3−2a+5+a−2b−3
3 Gather like terms
(-2a+a)+5-2b-3(−2a+a)+5−2b−3
4 Simplify
-a+5-2b-3−a+5−2b−3
5 Simplify
-a-2b+2−a−2b+2
16² = 18² + 19² - 2(18)(19)cos(z)
256 = 324 + 361 - (684)cos(z)
256 = 685 - (684)cos(z)
-429 = -684cos(z)
cos(z) = -429/-684
z = cos⁻¹ (0.627)
z = cos⁻¹ (cos 51) [ Cos 51 = 0.627 ]
z = 51
In short, Your Answer would be: 51
Hope this helps!
