Your answer is 75°.
To answer this question you need to use both the cosine rule and the sine rule. First, we need to find the length of side b by using the cosine rule, where a = 2 and c = √3 + 1. Then you substitute these into the equation:
b² = a² + c² - 2×a×c×cos(B)
b² = (2)² + (√3 + 1)² - 2×2×(√3 + 1)×cos(60)
b² = 4 + 4 + 2√3 - (4 - 4√3)×0.5
b² = 8 - 2 = 6
b = √6
Then you use this length in the sine rule, and find the angle:

sin(A) = (√6 + √2)/4
A = 75

Step-by-step explanation:
2x2 = 4
4-3=1
1a. The equation is x-35+x+5+x
1/4, 2/5, 0.5, 0.75
1/4 is 0.25
2/5 is 0.40
Then order from least to greatest.
