Question

plz help ill give u brainlist

Answer 1

a² + b² = c²
1² + b² = 2²
b² = 2² - 1²
b² = 4 - 1
b² = 3
b = √3 
b  1.73 (nearest hundredth)

Answer: b =  1.73

$\sin(\alpha) = \dfrac{\text {opp}}{\text{hyp}}$

$\sin(\alpha) = \dfrac{\text {1}}{\text{2}}$

$\alpha = \sin^{-1} \bigg ( \dfrac{1}{2} \bigg)$

$\alpha = 30 \textdegree$

Answer: 30°

$\cos(\beta) = \dfrac{\text {adj}}{\text{hyp}}$

$\cos(\beta) = \dfrac{\text {1}}{\text{2}}$

$\beta = \cos^{-1} \bigg ( \dfrac{1}{2} \bigg)$

$\beta = 60 \textdegree$

Answer: 60°
